GMAC LLC

GMAC was incorporated in 1997 under the Delaware General Corporation Law. On January 1, 1998, GMAC merged with its predecessor, which was originally incorporated in New York in 1919. On July 20, 2006, GMAC converted from a Delaware corporation to a Delaware limited liability company. As a result, all references to General Motors Acceptance Corporation in the accompanying prospectus and the documents incorporated by reference therein refer to GMAC LLC.

GMAC operates directly and through its subsidiaries and affiliates in which GMAC or General Motors Corporation has equity investments.

GMAC’s global activities include Automotive Finance, Mortgage and Insurance operations:

RECENT DEVELOPMENTS

On November 30, 2006, GM, GMAC, GM Finance Co. Holdings LLC, a Delaware limited liability company and a wholly owned subsidiary of GM (“Holdco”), and FIM Holdings LLC, a Delaware limited liability company (“Purchaser”), successfully completed a series of transactions pursuant to which GM has sold to Purchaser common limited liability company interests of GMAC representing 51% of the aggregate common limited liability company interests of GMAC for a purchase price of approximately $7.353 billion (the “Transactions”) subject to the terms and conditions set forth in the Purchase and Sale Agreement, dated April 2, 2006, by and among GM, GMAC, Holdco and Purchaser and filed as Exhibit 2.1 to GMAC’s Current Report on Form 8-K filed with the Securities and Exchange Commission on April 3, 2006 (the “Purchase Agreement”).

Purchaser is an investment vehicle formed for purposes of the Transactions by Cerberus FIM Investors, LLC and wholly owned subsidiaries of Aozora Bank Limited, Citigroup Inc. and The PNC Financial Services Group, Inc. (collectively, the “Investors”). Changes in the net book value of GMAC as of the closing date of the Transactions required certain payments to be made between GM and GMAC in order to maintain the net book value at the contractually agreed-upon level. In addition, Purchaser purchased preferred limited liability company interests of GMAC for a cash purchase price of $500 million and GM and GM Preferred Finance Co. Holdings Inc., a wholly owned subsidiary of GM, purchased preferred limited liability company interests of GMAC for a cash purchase price of $1.4 billion.

Prior to consummation of the Transactions, (i) GMAC distributed to GM certain assets with respect to automotive leases owned by GMAC and its affiliates, such assets having a net book value of approximately $4.1

Table of Contents

billion, (ii) GM assumed or retained certain of GMAC’s post-employment welfare benefits, (iii) GMAC transferred to GM certain entities that hold a fee interest in certain real properties, (iv) GMAC made distributions to GM for a portion of GMAC’s net income from September 30, 2005 to the date of consummation of the Transactions, (v) GM and its subsidiaries repaid certain indebtedness owing to GMAC such that the specified unsecured obligations owing to GMAC and its subsidiaries from GM and its U.S. subsidiaries are no greater than $1.5 billion and (vi) GMAC made a one-time distribution to GM of approximately $2.7 billion of cash primarily to reflect the increase in GMAC’s equity value resulting from the elimination of a portion of its net deferred tax liabilities arising from the conversion of GMAC and certain of its subsidiaries to limited liability company form. The total value of the cash proceeds and distributions to GM after repayment of certain intercompany obligations but before it purchased preferred limited liability company interests of GMAC is expected to be approximately $14 billion over three years, comprised of the $7.4 billion purchase price, the $2.7 billion cash dividend and other transaction-related cash flows including the monetization of certain retained assets.

RISK FACTORS

You should carefully consider the following risk factors and the information under the heading “Risk Factors” in our annual report on Form 10-K for the year ended December 31, 2005 and our quarterly reports on Form 10-Q for the three months ended March 31, 2006, six months ended June 30, 2006 and nine months ended September 30, 2006 which are incorporated by reference into this prospectus supplement and accompanying prospectus, as well as the other information included or incorporated by reference into this prospectus supplement and the accompanying prospectus, before making an investment decision. The following is not intended as, and should not be construed as, an exhaustive list of relevant risk factors. There may be other risks that a prospective investor should consider that are relevant to its own particular circumstances or generally.

The Notes are effectively junior to the existing and future liabilities of GMAC’s subsidiaries

The Notes are GMAC’s unsecured obligations and will rank equally in right of payment with all of GMAC’s other existing and future unsecured, unsubordinated obligations. The Notes are not secured by any of GMAC’s assets. Any future claims of secured lenders with respect to assets securing their loans will be prior to any claim of the holders of the Notes with respect to those assets.

GMAC’s subsidiaries are separate and distinct legal entities from GMAC. GMAC’s subsidiaries have no obligation to pay any amounts due on the Notes or to provide GMAC with funds to meet its payment obligations on the Notes, whether in the form of dividends, distributions, loans or other payments. In addition, any payment of dividends, loans or advances by GMAC’s subsidiaries could be subject to statutory or contractual restrictions. Payments to GMAC by its subsidiaries will also be contingent upon the subsidiaries’ earnings and business considerations. GMAC’s right to receive any assets of any of its subsidiaries upon their bankruptcy, liquidation or reorganization, and therefore the right of the holders of the Notes to participate in those assets, will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors. Because of the nature of GMAC’s lending and investment businesses, its subsidiaries often incur significant liabilities to those creditors. In addition, even if GMAC is a creditor of any of its subsidiaries, its right as a creditor would be subordinate to any security interest in the assets of its subsidiaries and any indebtedness of its subsidiaries senior to that held by GMAC. As of September 30, 2006, GMAC had approximately $95 billion in indebtedness, $17 billion of which was secured, and GMAC subsidiaries had approximately $154 billion in indebtedness, $114 billion of which was secured.

Our Credit Ratings May Not Reflect All Risks of Your Investments in the Notes

Our credit ratings are an assessment by rating agencies of our ability to pay our debts when due. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the Notes. These credit ratings may not reflect the potential impact of risks relating to structure or marketing of the Notes. Agency ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization. Each agency’s rating should be evaluated independently of any other agency’s rating.

An Active Trading Market May Not Develop for the Notes

The Notes are a new issue of securities for which there is no trading market. We can provide no assurance regarding the future development or maintenance of a market for the Notes or the ability of holders of the Notes to sell their Notes. If such a market were to develop, the Notes could trade at prices which may be higher or lower than the initial offering price depending on many factors independent of our creditworthiness, including, among other things:

USE OF PROCEEDS

We will receive net proceeds before expenses of $990,180,000 from the sale of the Notes. We estimate that our expenses will be approximately $500,000. The expected net proceeds from the sale of the Notes will be added to the general funds of GMAC and will be available for the purchase of receivables, the making of loans or the repayment of debt. Such proceeds initially may be used to reduce short-term borrowings or invested in short-term securities.

DESCRIPTION OF NOTES

General

The following description of the particular terms of the Notes offered hereby supplements and, to the extent that the terms are inconsistent, replaces, the description of the general terms and provisions of the Debt Securities set forth in the accompanying prospectus. The Notes are a series of the Debt Securities registered by GMAC in September 2003 to be issued on terms to be determined at the time of sale. Capitalized terms used but not defined in this section have the meanings assigned to them in the accompanying prospectus.

The Notes will be issued in an initial aggregate principal amount of $1,000,000,000. The Notes offered hereby will be issued pursuant to an Indenture dated as of July 1, 1982, as amended (the “Indenture”), which is more fully described in the accompanying prospectus.

The Indenture and the Notes are governed by, and construed in accordance with, the laws of the State of New York, United States.

The Notes will be redeemed at par at maturity on December 15, 2011. The Notes are not redeemable by GMAC prior to maturity. The Notes will bear interest, calculated on the basis of a 360-day year consisting of twelve 30-day months, from December 15, 2006 at the rate of 6.000% per year, payable on June 15 and December 15 of each year, the first payment to be made on June 15, 2007 in respect of the period from and including December 15, 2006 to but excluding June 15, 2007, to the persons in whose name the Notes are registered at the close of business on the first day of the calendar month next preceding such June 15 and December 15.

Book-Entry, Delivery and Form

The Notes will be offered and sold in principal amounts of $2,000 and integral multiples of $1,000 above that amount. The Notes will be issued in the form of one or more fully registered Global Notes (collectively, the “Global Notes”), which will be deposited with, or on behalf of, The Depository Trust Company, New York, New York (the “Depositary” or “DTC”) and registered in the name of Cede & Co., the Depositary’s nominee. Beneficial interests in the Global Notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in the Depositary. Investors may elect to hold interests in the Global Notes through DTC, Clearstream Banking, société anonyme, Luxembourg (“Clearstream”), or Euroclear Bank S.A./NV as operator of the Euroclear System (“Euroclear”) if they are participants of such systems, or indirectly through organizations which are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries. Clearstream’s and Euroclear’s depositaries will hold interests in customers’ securities accounts in the depositaries’ names on the books of the Depositary. Citibank, N.A. will act as depositary for Clearstream and J.P. Morgan Chase Bank will act as depositary for Euroclear (in such capacities, the “U.S. Depositaries”). Except as set forth below, the Global Notes may be transferred, in whole and not in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee. The transfer of Global Notes may be made at the office of the registrar according to the rules of the clearing systems.

Clearstream has advised that it is incorporated under the laws of the Grand Duchy of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream Participants”). Clearstream facilitates the clearance and settlement of securities transactions between Clearstream

S-10

Table of Contents

Participants through electronic book-entry changes in accounts of Clearstream Participants, eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (CSSF). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant, either directly or indirectly.

Distributions, to the extent received by the U.S. Depositary for Clearstream, with respect to the Notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures.

Euroclear has advised that it was created in 1968 to hold securities for its participants (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, eliminating the need for physical movement of certificates and eliminating any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./NV (the “Euroclear Operator”), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the “Cooperative”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Euroclear Operator has advised us that it is licensed by the Belgian Banking and Finance Commission to carry out banking activities on a global basis. As a Belgian bank, it is regulated and examined by the Belgian Banking Commission.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants and has no record of or relationship with persons holding through Euroclear Participants.

Distributions, to the extent received by the U.S. Depositary for Euroclear, with respect to Notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions.

The Bank of New York, the trustee, is the initial paying agent and transfer agent to the Notes.

Individual certificates in respect of Notes will not be issued in exchange for the Global Notes, except in very limited circumstances. If Euroclear, Clearstream or DTC notifies us that it is unwilling or unable to continue as a clearing system in connection with a Global Note or, in the case of DTC only, DTC ceases to be a clearing agency registered under the Securities Exchange Act, and in each case we do not appoint a successor clearing system within 90 days after receiving such notice from Euroclear, Clearstream or DTC or on becoming aware

S-11

Table of Contents

that DTC is no longer so registered, we will issue or cause to be issued individual certificates in registered form on registration of, transfer of or in exchange for book-entry interests in the Notes represented by such Global Note upon delivery of such Global Note for cancellation.

Title to book-entry interests in the Notes will pass by book-entry registration of the transfer within the records of Euroclear, Clearstream or DTC, as the case may be, in accordance with their respective procedures. Book-entry interests in the Notes may be transferred within Euroclear and within Clearstream and between Euroclear and Clearstream in accordance with procedures established for these purposes by Euroclear and Clearstream. Book-entry interests in the Notes may be transferred within DTC in accordance with procedures established for this purpose by DTC. Transfers of book-entry interests in the Notes between Euroclear and Clearstream and DTC may be effected in accordance with procedures established for this purpose by Euroclear, Clearstream and DTC.

Global Clearance and Settlement Procedures

Initial settlement for the Notes will be made in immediately available funds. Secondary market trading between DTC Participants will occur in the ordinary way in accordance with Depositary rules. Secondary market trading between Clearstream Participants and/or Euroclear Participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional Eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through the Depositary on the one hand, and directly or indirectly through Clearstream or Euroclear Participants, on the other, will be effected in the Depositary in accordance with the Depositary rules on behalf of the relevant European international clearing system by its U.S. Depositary. However, a cross-market transfer will require delivery of instructions to the relevant European international clearing system by the counterparty in such European international clearing system, in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. Depositary to take action to effect final settlement on its behalf by delivering or receiving Notes in the Depositary and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to the Depositary. Clearstream Participants and Euroclear Participants may not deliver instructions directly to their respective U.S. Depositaries.

Because of time-zone differences, credits of Notes received in Clearstream or Euroclear as a result of a transaction with a DTC Participant will be made during subsequent securities settlement processing and dated the business day following the Depositary settlement date. Credits or any transactions of the type described above settled during subsequent securities settlement processing will be reported to the relevant Euroclear or Clearstream Participants on the business day that the processing occurs. Cash received in Clearstream or Euroclear as a result of sales of Notes by or through a Clearstream Participant or a Euroclear Participant to a DTC Participant will be received with value on the Depositary settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in the Depositary.

Although the Depositary, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of Notes among participants of the Depositary, Clearstream and Euroclear, they are under no obligation to perform or continue to perform these procedures. The foregoing procedures may be changed or discontinued at any time.

Neither GMAC nor the Trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective direct or indirect participants of their obligations under the rules and procedures governing their operations.

Further Issues

We may from time to time, without notice to or the consent of the registered holders of the Notes, create and issue further Notes ranking equally with the Notes offered by this prospectus supplement in all respects, or in all respects except for the payment of interest accruing prior to the issue date of such further Notes or except, in some cases, for the first payment of interest following the issue date of such further Notes. Such further Notes may be consolidated and form a single series with the Notes offered by this prospectus supplement and have the same terms as to status, redemption or otherwise as the Notes offered by this prospectus supplement.

Notices

Notices to holders of the Notes will be published in authorized daily newspapers in The City of New York, in London. It is expected that publication will be made in The City of New York in The Wall Street Journal, in London in the Financial Times Any notice given pursuant to these provisions shall be deemed to have been given on the date of publication or, if published more than once, on the date first published.

Concerning the Trustee

The Trustee under the indenture is the Bank of New York. Pursuant to the Indenture, the Trustee will be designated by GMAC as the initial paying agent, transfer agent and registrar to the Notes. The Corporate Trust Office of the Trustee is currently located at 101 Barclay Street, Floor 7E, New York, N.Y. 10286, U.S.A. Attention: Trust Administration Department

The indenture provides that the Trustee, prior to the occurrence of an event of default and after the curing of all events of default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in the Indenture. If an event of default has occurred (which has not been cured), the Trustee will use the same degree of care and skill in its exercise of the rights and powers vested in it by the Indenture as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. The Indenture also provides that the Trustee or any agent of GMAC or the Trustee, in their individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee provided, however, that all moneys received by the Trustee or any paying agent shall, until used or applied as provided in the Indenture, be held in trust thereunder for the purposes for which they were received and need not be segregated from other funds except to the extent required by law.

Governing Law and Consent to Jurisdiction

The Indenture and the Notes are governed by and will be construed in accordance with the laws of the State of New York. Any claims or proceedings in respect of the indenture or the Notes shall be heard in a federal or state court located in the State of New York.

UNITED STATES FEDERAL TAXATION

The following summary describes the material United States federal income and certain estate tax consequences of ownership and disposition of the Notes. This summary provides general information only and is directed solely to original holders purchasing Notes at the “issue price”, that is, the first price to the public at which a substantial amount of the Notes in an issue is sold (excluding sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers). This summary is based on the United States Internal Revenue Code of 1986, as amended to the date hereof (the “Code”), existing administrative pronouncements and judicial decisions, existing and proposed Treasury Regulations currently in effect, and interpretations of the foregoing, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein, possibly with retroactive effect. This summary discusses only Notes held as capital assets within the meaning of Section 1221 of the Code. This

S-13

Table of Contents

summary does not discuss all of the tax consequences that may be relevant to a holder in light of the holder’s particular circumstances or to holders subject to special rules, such as certain financial institutions, insurance companies, dealers in securities, traders in securities who have elected to use the mark-to-market method of accounting, persons holding Notes in connection with a hedging transaction, “straddle,” conversion transaction or other integrated transaction, persons who have ceased to be United States citizens or to be taxed as resident aliens and United States persons whose functional currency (as defined in Section 985 of the Code) is not the U.S. dollar.

Persons considering the purchase of Notes should consult their tax advisors with regard to the application of the United States federal income and estate tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Tax Consequences to United States Persons

For purposes of the following discussion, “United States person” means a beneficial owner of a Note that is for United States federal income tax purposes:

If a partnership holds Notes, the tax treatment of a partner will generally depend upon the status of the partner and upon the activities of the partnership. Partners of partnerships holding Notes should consult their tax advisors.

Payments of Interest

Interest on a Note will generally be taxable to a United States person as ordinary interest income at the time it is accrued or is received in accordance with the United States person’s method of accounting for tax purposes.

Sale, Exchange or Retirement of the Notes

Upon the sale, exchange or retirement of a Note, a United States person will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange or retirement and the United States person’s adjusted tax basis in the Note. For these purposes, the amount realized does not include any amount attributable to interest on the Note that has not previously been included in income, which will be includable as interest as described under “Payments of Interest” above. A United States person’s adjusted tax basis in a Note generally will equal the cost of the Note to the United States person.

In general, gain or loss realized on the sale, exchange or redemption of a Note will be capital gain or loss. Prospective investors should consult their tax advisors regarding the treatment of capital gains (which may be taxed at lower rates than ordinary income for taxpayers who are individuals, trusts or estates) and losses (the deductibility of which is subject to limitations).

Table of Contents

Backup Withholding and Information Reporting

Backup withholding and information reporting requirements may apply to certain payments of principal, premium and interest on a Note, and to payments of proceeds of the sale or redemption of a Note, to certain non-corporate United States persons. GMAC, its agent, a broker, or any paying agent, as the case may be, will generally be required to withhold from any payment a tax equal to 28% of such payment if the United States person fails to furnish or certify his correct taxpayer identification number to the payor in the manner required, fails to certify that such United States person is not subject to backup withholding, or otherwise fails to comply with the applicable requirements of the backup withholding rules. Any amounts withheld under the backup withholding rules from a payment to a United States person may be credited against that United States person’s United States federal income tax and may entitle that United States person to a refund, provided that the required information is furnished to the United States Internal Revenue Service (“IRS”).

Tax Consequences to Non-United States Persons

As used herein, the term “non-United States person” means an owner of a Note that is, for United States federal income tax purposes:

The term “non-United States Person” does not include a beneficial owner who (i) actually or constructively owns 10% or more of the profits or capital interests in GMAC or (ii) is a controlled foreign corporation related, directly or indirectly, to GMAC through stock ownership.

If a partnership holds Notes, the tax treatment of a partner will generally depend upon the status of the partner and upon the activities of the partnership. Partners of partnerships holding Notes should consult their tax advisors.

Income and Withholding Tax

Subject to the discussion of backup withholding below:

provided that in each such case, the relevant certification or IRS form is delivered pursuant to applicable procedures and is properly transmitted to the person otherwise required to withhold

S-15

Table of Contents

United States federal income tax, and none of the persons receiving the relevant certification or IRS form has actual knowledge that the certification or any statement on the IRS form is false;

With respect to the certification requirement referred to in subparagraph (a), for Notes held by a foreign partnership, unless the foreign partnership has entered into a withholding agreement with the IRS, a foreign partnership will be required, in addition to providing a Form W-8IMY, to attach an appropriate certification by each partner. Prospective investors, including foreign partnerships and their partners, should consult their tax advisors regarding possible additional reporting requirements.

If a non-United States person holding a Note is engaged in a trade or business in the United States, and if interest on the Note (or gain realized on its sale, exchange or other disposition) is effectively connected with the conduct of such trade or business, such holder, although exempt from the withholding tax discussed in the preceding paragraphs, will generally be subject to regular United States income tax on such effectively connected income in the same manner as if it were a United States person. Such a holder may also need to provide a United States taxpayer identification number on the forms referred to in paragraph (a) above in order to meet the requirements set forth above. In addition, if such holder is a foreign corporation, it may be subject to a 30% branch profits tax (unless reduced or eliminated by an applicable treaty) on its effectively connected earnings and profits for the taxable year, subject to certain adjustments. For purposes of the branch profits tax, interest on, and any gain recognized on the sale, exchange or other disposition of, a Note will be included in the effectively connected earnings and profits of such holder if such interest or gain, as the case may be, is effectively connected with the conduct by such holder of a trade or business in the United States.

Each holder of a Note should be aware that if it does not properly provide the required IRS form, or if the IRS form or, if permissible, a copy of such form, is not properly transmitted to and received by the United States person otherwise required to withhold United States federal income tax, interest on the Note may be subject to United States withholding tax at a 30% rate. Such tax, however, may in certain circumstances be allowed as a refund or as a credit against such holder’s United States federal income tax.

The foregoing does not deal with all aspects of federal income tax withholding that may be relevant to non-United States persons who hold the Notes. Investors are advised to consult their own tax advisors for specific advice concerning the ownership and disposition of Notes.

Backup Withholding and Information Reporting

Under current Treasury Regulations, backup withholding (imposed at the rate of 28%) will not apply to payments made by GMAC or a paying agent to a non-United States person in respect of a Note if the certifications described above are received, provided in each case that GMAC or the paying agent, as the case may be, does not have actual knowledge that the payee is a United States person.

Under current Treasury Regulations, payments of the proceeds from the sale, exchange or other disposition of a Note made to or through a foreign office of a broker (including a custodian, nominee or other agent acting on behalf of the beneficial owner of a Note) generally will not be subject to information reporting or backup withholding. However, if such broker is a United States person, a controlled foreign corporation for United States federal tax purposes, a foreign person 50% or more of whose gross income is effectively connected with a United States trade or business for a specified three-year period, or a foreign partnership with certain connections with the United States, then information reporting will be required unless the broker has in its records documentary evidence that the beneficial owner is not a United States person and certain other conditions are met or the beneficial owner otherwise establishes an exemption. Backup withholding may apply to any payment that such broker is required to report if such broker has actual knowledge that the payee is a United States person. Payments to or through the United States office of a broker are subject to information reporting and backup withholding unless the holder or beneficial owner certifies, under penalties of perjury, that it is a non-United States person and that it satisfies certain other conditions or otherwise establishes an exemption from information reporting and backup withholding.

Non-United States persons holding Notes should consult their tax advisors regarding the application of information reporting and backup withholding in their particular situations, the availability of an exemption therefrom, and the procedure for obtaining such an exemption, if available. Backup withholding is not a separate tax, but is allowed as a refund or credit against the holder’s United States federal income tax, provided the necessary information is furnished to the IRS.

Interest on a Note that is beneficially owned by a non-United States person will be reported annually on IRS Form 1042S, which must be filed with the IRS and furnished to such beneficial owner.

UNDERWRITING

Subject to the terms and conditions set forth in an underwriting agreement dated December 12, 2006 (the “Underwriting Agreement”), we have agreed to sell to each of the underwriters named below, and each of the underwriters, for whom Banc of America Securities LLC, Citigroup Global Markets Inc. and J.P. Morgan Securities Inc. are acting as representatives (collectively, the “Representatives”), has severally agreed to purchase the principal amount of Notes set forth opposite its name below. In the Underwriting Agreement, the several underwriters have agreed, subject to the terms and conditions set forth therein, to purchase all the Notes offered hereby if any of the Notes are purchased.

The Representatives of the underwriters have advised us that the underwriters propose initially to offer the Notes to the public at the offering price set forth on the cover page of this prospectus supplement and to certain dealers at such price less a concession not in excess of 0.25% of the principal amount of the Notes. The underwriters may allow, and such dealers may reallow, a concession not in excess of 0.20% of the principal amount of the Notes to certain other dealers. After the initial public offering, the public offering price and concession may be changed.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended.

The Notes are offered for sale in those jurisdictions in the United States, Europe, Asia and Canada where it is legal to make such offers. Only offers and sales of the Notes in the United States, as part of the initial distribution thereof or in connection with resales thereof under circumstances where this prospectus supplement and the accompanying prospectus must be delivered, are made pursuant to the registration statement of which the accompanying prospectus, as supplemented by this prospectus supplement, is a part.

Each underwriter has represented and agreed that it will comply with all applicable laws and regulations in force in any jurisdiction in or from which it purchases, offers, sells or delivers the Notes or any interest therein or possesses or distributes this prospectus supplement or the accompanying prospectus or any offering material relating to the Notes and will obtain any consent, approval or permission required by it for the purchase, offer or sale by it of the Notes under the laws and regulations in force in any jurisdiction to which it is subject or in which it makes such purchases, offers or sales and neither GMAC nor any other underwriter shall have responsibility therefor.

The Notes are a new issue of securities with no established trading market. No assurance can be given as to the liquidity of, or the trading markets for, the Notes. We have been advised by the underwriters that they intend to make a market in the Notes, but they are not obligated to do so and may discontinue such market-making at any time without notice.

To the extent any underwriter that is not a U.S.-registered broker-dealer intends to effect sales of notes in the United States, it will do so through one or more U.S.-registered broker-dealers in accordance with the applicable U.S. securities laws and regulations.

Table of Contents

Purchasers of the Notes may be required to pay stamp taxes and other charges in accordance with the laws and practices of the country of purchase in addition to the issue prices set forth on the cover page of this prospectus supplement.

In connection with the sale of the Notes, certain of the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Notes. Specifically, the underwriters may overallot the offering, creating a short position. In addition, the underwriters may bid for and purchase the Notes in the open market to cover short positions or to stabilize the price of the Notes. Any of these activities may stabilize or maintain the market price of the Notes above independent market levels. The underwriters will not be required to engage in these activities, and may end any of these activities at any time.

Neither we nor any underwriter makes any prediction as to the direction or magnitude of any effect that the transactions described in the immediately preceding paragraph may have on the price of the Notes.

In the ordinary course of their respective businesses, the underwriters have engaged, and will in the future engage, in commercial banking and investment banking transactions with us and certain of our affiliates for which they have received customary fees and expenses.

We may initially use the proceeds to reduce short-term borrowings or to invest in short-term securities.

DESCRIPTION OF DEBT SECURITIES

The debt securities offered are to be issued under an Indenture dated as of July 1, 1982, as amended by:

5

Table of Contents

and as further amended by the Trust Indenture Reform Act of 1990, as amended (together, the “Indenture”), between us and The Bank of New York, Successor Trustee (the “Trustee”), copies of which are filed as exhibits to the registration statement. We have summarized certain terms and provisions of the Indenture; such summaries are not complete and are subject to all provisions of the Indenture, including the definition of certain terms. You should read the indenture for the provisions which may be important to you. The Indenture is subject to and governed by the Trust Indenture Reform Act of 1990, as amended.

The Indenture provides that, in addition to the debt securities being offered, additional debt securities may be issued without limitation as to aggregate principal amount, but only as authorized by our Board of Directors.

General

Reference is made to the accompanying prospectus supplement for the following terms of the debt securities being offered:

Principal and interest, if any, will be payable, and, unless the debt securities are issued in book-entry form, the debt securities being offered will be transferable, at the principal corporate trust office of the Trustee, which at the date hereof is 101 Barclay Street, New York, New York 10286, provided that payment of interest may be made at our option by check mailed to the address of the person entitled thereto.

The debt securities will be unsecured and unsubordinated and will rank pari passu with all our other unsecured and unsubordinated obligations (other than obligations preferred by mandatory provisions of law).

Some of the debt securities may be issued as discounted debt securities, bearing no interest or interest at a rate, which at the time of issuance, is below market rates, to be sold at a substantial discount below their stated principal amount. Federal income tax consequences and other special considerations applicable to any such discounted debt securities will be described in the accompanying prospectus supplement.

Debt securities will include debt securities denominated in United States dollars or, at our option if so specified in the accompanying prospectus supplement, in any other currency.

6

Table of Contents

If a prospectus supplement specifies that debt securities are denominated in a currency other than United States dollars, the prospectus supplement will also specify the denomination in which such debt securities will be issued and the coin or currency in which the principal, premium, if any, and interest on the debt securities, where applicable, will be payable, which may be United States dollars based upon the exchange rate for such other currency existing on or about the time a payment is due.

If a prospectus supplement specifies that the debt securities will have a redemption option, our election to exercise such an option will constitute an issuer tender offer under the Exchange Act. We will comply with all issuer tender offer rules and regulations under the Exchange Act, including Rule 14e-1, if such redemption option is elected. We will make any required filings with the SEC and furnish certain information to the holders of the debt securities.

Book-Entry, Delivery and Form

Unless otherwise indicated in the accompanying prospectus supplement, the debt securities and warrants will be issued in the form of one or more fully registered global securities (each a “Global Debt Security”) which will be deposited with, or on behalf of, The Depository Trust Company, New York, New York (the “Depositary” or “DTC”) and registered in the name of the Depositary’s nominee. Beneficial interests in a Global Debt Security will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants of the Depository. Investors may elect to hold interests in a Global Debt Security through DTC. Except as set forth below, a Global Debt Security may be transferred, in whole and not in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee.

DTC is a limited-purpose trust company organized under the laws of the State of New York, a “banking organization” within the meaning of the New York Banking Law, member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency”, registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC was created to hold securities of institutions, called participants, and to facilitate the clearance and settlement of securities transactions, such as transfers and pledges, between participants through electronic computerized book-entry changes in the accounts of its participants, thereby eliminating the need for physical movement of certificates. Participants include:

Access to the Depositary’s system is also available to others such as banks, brokers, dealers and trust companies, called indirect participants, that clear through or maintain a custodial relationship with a participant, either directly or indirectly. Persons who are not participants may beneficially own securities held by the Depositary only through participants or indirect participants.

The Depositary advises that pursuant to procedures established by it:

7

Table of Contents

The laws of some states require that certain persons take physical delivery in definitive form of securities which they own. Consequently, the ability to transfer beneficial interests in a Global Debt Security is limited to such extent.

As long as the Depositary’s nominee is the registered owner of a Global Debt Security, such nominee for all purposes will be considered the sole owner or holder of the debt securities represented by a Global Debt Security. Except as provided below, you will not:

Neither we, the Trustee, any Paying Agent, warrant agent or any other agent for payment on or registration of transfer or exchange of any Global Debt Security nor the Depositary will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Debt Security, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Principal, premium, if any, and interest payments on the debt securities registered in the name of the Depositary’s nominee will be made by the Trustee to the Depositary’s nominee as the registered owner of the Global Debt Security. Under the terms of the Indenture, we and the Trustee will treat the persons in whose names the debt securities are registered as the owners of the debt securities for the purpose of receiving payment of principal, premium, if any, and interest on the debt securities and for all other purposes whatsoever. Therefore, we do not have, and neither the Trustee nor any Paying Agent has, any direct responsibility or liability for the payment of principal, premium, if any, or interest on the debt securities to owners of beneficial interests in the Global Debt Security. The Depositary has advised us and the Trustee that its present practice is, upon receipt of any payment of principal or interest, to immediately credit the accounts of the Participants with such payment in amounts proportionate to their respective holdings in principal amount of beneficial interests in the Global Debt Security as shown on the records of the Depositary. Payments by participants and indirect participants to owners of beneficial interests in the Global Debt Security will be the responsibility of such participants and indirect participants and will be governed by their standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name”.

If the Depositary is at any time unwilling or unable to continue as depositary and we have not appointed a successor depositary within 90 days, we will issue debt securities in definitive form in exchange for the Global Debt Security. In addition, we may at any time determine not to have the debt securities represented by the Global Debt Security and, in such event, will issue debt securities in definitive form in exchange for the Global Debt Security. In either instance, an owner of a beneficial interest in a Global Debt Security will be entitled to have debt securities equal in principal amount to the beneficial interest registered in its name and will be entitled to physical delivery of the debt securities in definitive form. Debt securities so issued in definitive form will be issued in denominations of $1,000 and integral multiples thereof and will be issued in registered form only, without coupons. No service charge will be made for any transfer or exchange of the debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Limitation on Liens

The only financial covenant applicable to the debt securities is that described below. That covenant requires that the debt securities be equally and ratably secured in the circumstances described therein but has no special application merely by virtue of the occurrence of any transaction or series of transactions resulting in material changes in GMAC’s debt-to-equity ratio.

8

Table of Contents

The debt securities are not secured by mortgage, pledge or other lien.

GMAC will covenant in the debt securities that so long as any of the debt securities remain outstanding, it will not pledge or otherwise subject to any lien any of its property or assets unless the debt securities are secured by such pledge or lien equally and ratably with any and all other obligations and indebtedness secured thereby so long as any such other obligations and indebtedness shall be so secured. Such covenant does not apply to:

Merger and Consolidation

The Indenture provides that we will not merge or consolidate with another corporation or sell or convey all or substantially all of our assets unless either we are the continuing corporation or the new corporation shall expressly assume the interest and principal due under the securities. In either case, the Indenture provides that neither we nor a successor corporation may be in default of performance immediately after a merger or consolidation. Additionally, the Indenture provides that in the case of any such merger or consolidation, either we or the successor company may continue to issue securities under the Indenture.

Modification of the Indenture

The Indenture contains provisions permitting us and the Trustee to modify or amend the Indenture or any supplemental indenture or the rights of the holders of the debt securities issued thereunder, with the consent of the holders of not less than 66 ²/3% in aggregate principal amount of the debt securities of all series at the time outstanding under such Indenture which are affected by such modification or amendment, voting as one class, provided that, without the consent of the holder of each debt security so affected, no such modification shall:

9

Table of Contents

The Indenture contains provisions permitting us and the trustee to enter into indentures supplemental to the Indenture, without the consent of the holders of the debt securities at the time outstanding, for one or more of the following purposes:

Events of Default

An event of default with respect to any series of debt securities issued subject to the Indenture is defined in the Indenture as being:

No event of default with respect to a particular series of debt securities issued under the Indenture necessarily constitutes an event of default with respect to any other series of debt securities issued thereunder. In case an event of default as set out in the first, second and third items listed above shall occur and be continuing with respect to any series, the Trustee or the holders of not less than 25% in aggregate principal amount of debt securities of each such series then outstanding may declare the principal, or, in the case of discounted debt securities, the amount specified in the terms thereof, of such series to be due and payable. In case an event of default as set out in the fourth item listed above shall occur and be continuing, the Trustee or the holders of not less than 25% in aggregate principal amount of all the debt securities then outstanding, voting as one class, may declare the principal, or, in the case of discounted debt securities, the amount specified in the terms thereof, of all outstanding debt securities to be due and payable. Any event of default with respect to a particular series of debt securities may be waived and a declaration of acceleration of payment rescinded by the holders of a majority in aggregate principal amount of the outstanding debt securities of such series, or of all the outstanding debt securities, as the case may be, if sums sufficient to pay all amounts due other than amounts due upon acceleration are provided to the trustee and all defaults are remedied. For such purposes, if the principal of all series shall have been declared to be payable, all series shall be treated as a single class. We are required to file with the

10

Table of Contents

Trustee annually an officers’ certificate as to the absence of certain defaults under the terms of the Indenture. The Indenture provides that the Trustee may withhold notice to the securityholders of any default, except in payment of principal, premium, if any, or interest, if it considers it in the interest of the securityholders to do so.

Subject to the provisions of the Indenture relating to the duties of the Trustee in case an Event of Default shall occur and be continuing, the Trustee shall be under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the securityholders, unless such securityholders shall have offered to the Trustee reasonable indemnity or security.

Subject to such provisions for the indemnification of the Trustee and to certain other limitations, the holders of a majority in principal amount of the debt securities of each series affected, with each series voting as a separate class, at the time outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee.

Further Issues

We may from time to time, without notice to or the consent of the registered holders of the applicable series of debt securities, create and issue further debt securities of each series of debt securities ranking pari passu with the debt securities of the applicable series in all respects, or in all respects except for the payment of interest accruing prior to the issue date of such further debt securities or except for the first payment of interest following the issue date of such further debt securities. Such further debt securities may be consolidated and form a single series with the debt securities of the applicable series and have the same terms as to status, redemption or otherwise as the debt securities of that series.

Concerning the Trustee

The Bank of New York is the Successor Trustee under the Indenture. It is also Successor Trustee under various other indentures covering our outstanding notes and debentures. The Bank of New York and its affiliates act as depository for funds of, make loans to, act as trustee and perform certain other services for, certain of our affiliates and us in the normal course of its business. As trustee of various trusts, it has purchased our securities and those of certain of our affiliates.

DESCRIPTION OF WARRANTS

General

The following statements with respect to the warrants are summaries of the detailed provisions of one or more separate warrant agreements (each a “Warrant Agreement”) between us and a banking institution organized under the laws of the United States or one of the states thereof (each a “Warrant Agent”), a form of which is filed as an exhibit to the registration statement. Wherever particular provisions of the Warrant Agreement or terms defined therein are referred to, such provisions or definitions are incorporated by reference as a part of the statements made, and the statements are qualified in their entirety by such reference.

The warrants will be evidenced by warrant certificates (the “Warrant Certificates”) and, except as otherwise specified in the prospectus supplement accompanying this prospectus, may be traded separately from any debt securities with which they may be issued. Warrant Certificates may be exchanged for new Warrant Certificates of different denominations at the office of the Warrant Agent. The holder of a warrant does not have any of the rights of a holder of a debt security in respect of, and is not entitled to any payments on, any debt securities issuable, but not yet issued, upon exercise of the warrants.

11

Table of Contents

The warrants may be issued in one or more series, and reference is made to the prospectus supplement accompanying this prospectus relating to the particular series of warrants, if any, offered thereby for the terms of, and other information with respect to, such warrants, including:

Exercise of Warrants

Warrants may be exercised by payment to the Warrant Agent of the exercise price, in each case in such currency or currencies as are specified in the warrant, and by communicating to the Warrant Agent the identity of the warrantholder and the number of warrants to be exercised. Upon receipt of payment and the Warrant Certificate properly completed and duly executed, at the office of the Warrant Agent, the Warrant Agent will, as soon as practicable, arrange for the issuance of the applicable debt securities, the form of which shall be set forth in the prospectus supplement. If less than all of the warrants evidenced by a Warrant Certificate are exercised, a new Warrant Certificate will be issued for the remaining amount of Warrants.

PLAN OF DISTRIBUTION

We may offer from time to time debt securities and warrants. The aggregate initial offering price of all securities sold by us under this prospectus will not exceed $20,000,000,000.

A prospectus supplement will set forth the terms of the offering of the securities described in this prospectus, including:

12

Table of Contents

Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

We may sell the securities being offered in five ways:

Direct Sales

We may directly solicit offers to purchase securities. In this case, no underwriters or agents would be involved.

By Agents

We may use agents to sell the securities. Any such agent, who may be deemed to be an underwriter as that term is defined in the Securities Act of 1933, involved in the offer or sale of the securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to such agent set forth, in the prospectus supplement. Unless otherwise indicated in the prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment, which is ordinarily three business days or less.

By Underwriters

If an underwriter or underwriters are utilized in the sale, we will enter into an underwriting agreement with such underwriters at the time of sale to them and the names of the underwriters and the terms of the transaction will be set forth in the prospectus supplement, which will be used by the underwriters to make resales of the securities in respect of which this prospectus is delivered to the public.

If underwriters are used in the sale of any securities, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The securities may be either offered to the public through underwriting syndicates represented by managing underwriters or directly by underwriters. Generally, the underwriters’ obligations to purchase the securities will be subject to certain conditions precedent. The underwriters will be obligated to purchase all of the securities if they purchase any of the securities.

By Dealers

If a dealer is utilized in the sale of the securities in respect of which this prospectus is delivered, we will sell such securities to the dealer as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

Delayed Delivery Contracts

If so indicated in the prospectus supplement, we will authorize agents and underwriters to solicit offers by certain institutions to purchase securities from us at the public offering price set forth in the prospectus supplement

13

Table of Contents

pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the prospectus supplement. Each delayed delivery contract will be for an amount not less than the respective amounts stated in the prospectus supplement. Unless we otherwise agree, the aggregate principal amount of securities sold pursuant to delayed delivery contracts shall be not less nor more than the respective amounts stated in the prospectus supplement. Institutions with whom delayed delivery contracts, when authorized, may be made include:

All delayed delivery contracts are subject to our approval. Delayed delivery contracts will not be subject to any conditions except that the purchase by an institution of the securities covered by its delayed delivery contract shall not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which such institution is subject. A commission indicated in the prospectus supplement will be paid to underwriters and agents soliciting purchases of securities pursuant to contracts accepted by us.

Through the Internet or Bidding or Ordering System

We may also offer debt securities directly to the public, with or without the involvement of agents, underwriters or dealers, and may utilize the Internet or another electronic bidding or ordering system for the pricing and allocation of such debt securities. Such a system may allow bidders to directly participate, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us, and which may directly affect the price or other terms at which such securities are sold.

The final offering price at which debt securities would be sold and the allocation of debt securities among bidders, would be based, in whole or in part, on the results of the Internet bidding process or auction. Many variations of the Internet auction or pricing and allocating systems are likely to be developed in the future, and we may utilize such systems in connection with the sale of debt securities. We will describe in the related supplement to this prospectus how any auction or bidding process will be conducted to determine the price or any other terms of the debt securities, how potential investors may participate in the process and, where applicable, the nature of the underwriters’ obligations with respect to the auction or ordering system.
