Registration Statement on Form S-3 (No. 142062)

Ladies and Gentlemen:

We have acted as special counsel for Capital One Auto Receivables, LLC, a Delaware limited liability company (the “Company”), in connection with (a) the above-captioned registration statement and (b) the offering of notes (the “Notes”) described in the related prospectus supplement dated September 25, 2007 and prospectus dated September 24, 2007 (collectively, the “Prospectus”), which have been filed with the Securities and Exchange Commission pursuant to Rule 424(b) under the Securities Act of 1933, as amended. As described in the Prospectus, the Notes will be issued on or about October 4, 2007 by Capital One Prime Auto Receivables Trust 2007-2 (the “Trust”), a trust formed by the Company pursuant to a trust agreement between the Company and Wilmington Trust Company, as owner trustee. The Notes will be issued pursuant to an indenture (the “Indenture”) between the Trust and Deutsche Bank Trust Company Americas, as indenture trustee.

In that connection, we are generally familiar with the proceedings taken or to be taken in connection with the proposed authorization, issuance and sale of the Notes and have examined copies of such documents, corporate records and other instruments as we have deemed necessary or appropriate for the purposes of this opinion, including the Prospectus and the current draft of the Indenture (including the form of Notes included as exhibits thereto).

Based on and subject to the foregoing, we are of the opinion that, when 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, and payment of the agreed consideration for the Notes shall have been received by the Trust, 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.

Mayer Brown LLP operates in combination with our associated English limited liability partnership.
