None

Part III

Substitute information provided in accordance with General Instruction J to Form 10-K:

Item 1119 of Regulation AB. Affiliations and Certain Relationships and Related Transactions.

Information required by Item 1119 of Regulation AB has been omitted from this report on Form 10-K in reliance on the Instruction to Item 1119. The information has been provided previously in a prospectus, dated May 31, 2007, filed by the Issuing Entity, pursuant to Rule 424(b)(5) of the Securities Act of 1933, on June 4, 2007.

Item 1122 of Regulation AB. Compliance with Applicable Servicing Criteria.

Each of GMAC and the Indenture Trustee (each, a “Servicing Participant”) has been identified by the registrant as a party participating in the servicing function with respect to the pool assets held by the Issuing Entity during the reporting period. Each of the Servicing Participants has completed a report on an assessment of compliance with the servicing criteria applicable to such Servicing Participant (each, a “Report on Assessment”) during the Issuing Entity’s year ended December 31, 2007, which Reports on Assessment are attached as exhibits to this Form 10-K. In addition, each of the Servicing Participants has provided an attestation

3

report (each, an “Attestation Report”) by a registered independent public accounting firm regarding its related Report on Assessment. Each Attestation Report is attached as an exhibit to this Form 10-K.

GMAC’s Report on Assessment and the related Attestation Report have identified three instances of material noncompliance with the servicing criteria applicable to GMAC. Processes and procedures have been implemented to reinforce and ensure that all instances of material non-compliance are remediated. The instances of noncompliance are;

• Reconciliations on certain custodial accounts were not always completed within the required timeframe, reviewed and approved by someone other than the person who prepared the reconciliation, and reconciling items were not always reviewed and cleared within the required timeframe.

• Certain returned insurance premiums were not remitted in accordance with the transaction agreements.

• Certain investor reports had been revised during the year indicating an error in the initial investor report.

The Indenture Trustee Report on Assessment identified an additional material noncompliance. Specifically, collections received on assets relating to a certain series of securities were deposited into a general account rather than the segregated account for each specific series. Processes have been implemented or are in place and being reinforced to ensure that all instances of noncompliance are remediated.

Item 1123 of Regulation AB. Servicer Compliance Statement.

GMAC has been identified as the servicer during the reporting period with respect to the pool assets held by the Issuing Entity. GMAC has provided a statement of compliance with the applicable servicing activities (the “Compliance Statement”), signed by an authorized officer, and such Compliance Statement is attached as an exhibit to this Form 10-K.
