Registration Statement on Form SF-3 (No. 333-________)

Ladies and Gentlemen:

We have acted as special federal tax counsel to Capital One Auto Receivables, LLC, a Delaware limited liability company (the “Company”), in connection with the above-captioned registration statement (such registration statement, together with the exhibits and any amendments thereto, the “Registration Statement”) filed by the Company with the Securities and Exchange Commission in connection with the registration by the Company of asset-backed notes (the “Notes”). As described in the Registration Statement, the Notes will be issued from time to time in series, with each series being issued by a statutory trust (each, a “Trust”) to be formed by the Company pursuant to a trust agreement (as amended, restated or otherwise modified, the “Trust Agreement”) between the Company and a trustee. The Notes will be issued pursuant to an indenture (each, an “Indenture”) between the related Trust and a financial institution acting as indenture trustee (the “Indenture Trustee”).

In that connection, we generally are familiar with the proceedings required to be taken in connection with the proposed authorization, issuance and sale of any series of Notes and have examined copies of such documents, corporate records and other instruments as we have deemed necessary or appropriate for the purpose of this opinion, including the Registration Statement and, in each case as filed as an exhibit to the Registration Statement, the form of Underwriting Agreement, the form of Indenture (including the form of Notes included as an exhibit thereto), the form of Amended and Restated Trust Agreement, the form of Sale Agreement, the form of Purchase Agreement, the form of Servicing Agreement, the form of Administration Agreement and the form of Asset Representations Review Agreement (collectively, the “Operative Documents”). Terms used herein without definition have the meanings given to such terms in the Registration Statement.

The opinion set forth herein is based upon the applicable provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations promulgated and proposed thereunder, current positions of the Internal Revenue Service (the “IRS”) contained in published Revenue Rulings and Revenue Procedures, current administrative positions of the IRS

Mayer Brown is a global services provider comprising an association of legal practices that are separate entities including

and existing judicial decisions. No tax rulings will be sought from the IRS with respect to any of the matters discussed herein. The statutory provisions, regulations and interpretations on which our opinions are based are subject to change, which changes could apply retroactively. In addition, there can be no assurance that positions contrary to those stated in our opinions may not be taken by the IRS.

Based on the foregoing and assuming that the Operative Documents with respect to each series are executed and delivered in substantially the form we have examined and that the transactions contemplated to occur under the Operative Documents in fact occur in accordance with the terms thereof, to the extent that the statements set forth in the Prospectus forming part of the Registration Statement under the captions “Summary of Terms—Tax Status” and “Material United States Federal Income Tax Consequences” constitute matters of U.S. federal income tax law or legal conclusions with respect thereto relating to U.S. federal tax matters, and to the extent such statements expressly state our opinions or state that our opinion has been or will be provided as to the Notes, we hereby confirm and adopt the opinions set forth therein (subject to the qualifications, assumptions, limitations and exceptions set forth therein).
