In that regard, we generally are familiar with the proceedings taken or required to be taken in connection with the proposed authorization, issuance and sale of the Notes and have examined and relied upon copies of such statutes, documents, corporate records and other instruments as we have deemed necessary or appropriate for the purposes of this opinion, including the Prospectus and current drafts of the Indenture (including the form of the Notes included as an exhibit thereto), the Amended and Restated Trust Agreement (including the form of Certificate included as an exhibit thereto), the Receivables Purchase Agreement, the Sale and Servicing Agreement, the Asset Representations Review Agreement and the Owner Trust Administration Agreement (collectively, the “Operative Documents”).

Based on and subject to the foregoing, we are of the opinion that, with respect to the Notes, when (a) the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, (b) the Notes have been duly executed and issued by the Trust and authenticated by the Indenture Trustee and sold by the Company or by the Trust, at the direction of the Company, as applicable, and (c) payment of the agreed consideration for the Notes shall have been received by the Trust, all in accordance with the terms and conditions of the related Operative Documents and a definitive purchase, underwriting or similar agreement with respect to the Notes and in the manner described in the Prospectus, the Notes will have been duly authorized by all necessary action of the Trust and will be legally issued and binding obligations of the Trust and entitled to the benefits afforded by the Indenture, except as may be limited by bankruptcy, insolvency, reorganization, arrangement, moratorium or other laws relating to or affecting creditors’ rights generally (including, without limitation, fraudulent conveyance laws), and by general principles of equity, regardless of whether such matters are considered in a proceeding in equity or at law.

Our opinions expressed herein are limited to the federal laws of the United States and the laws of the State of New York and the State of Delaware. We hereby consent to the filing of this opinion with the Commission as Exhibit 5.1 to a Form 8-K filed in connection with the Prospectus and to the use of our name therein without admitting we are “experts” within the meaning of the Act, or the rules and regulations of the Commission issued thereunder, with respect to any part of the Registration Statement or the Prospectus.

Very truly yours,

/s/ Mayer Brown LLP
