We have also considered such questions of law for the purpose of rendering the opinions expressed herein as we have deemed necessary.  For purposes of this opinion, “Applicable Laws” means those laws, rules and regulations which, in our experience, are normally applicable to transactions of the type contemplated by the Transaction Documents, without our having made any special investigation as to the applicability of any specific law, rule or regulation, and which are not the subject of a specific opinion herein referring expressly to a particular law or laws and, in the case of the Applicable Laws of the State of Delaware, shall be limited to the General Corporation Law and the Limited Liability Company Act of the State of Delaware; and “Governmental Approval” means any consent, approval, license, authorization or validation of, or filing, qualification or registration with, any court, regulatory body, administrative agency or governmental body pursuant to the Applicable Laws of the State of New York or the State of Delaware or the Applicable Laws of the United States of America.

In rendering the opinions expressed herein, we have assumed (a) that each of the parties to the Transaction Documents is duly organized, validly existing and in good standing under the laws of all jurisdictions where it is required to be so qualified and has full power and authority and has received all consents (and such consents remain in full force and effect) necessary to execute, deliver and perform under such documents and all such documents have been duly authorized by all necessary corporate or other action on the part of such parties, (b) the due authorization, execution and delivery of each of the Transaction Documents by each of the parties thereto and the due authentication of the Series 2013-1 Notes and each other Series of Notes by or on behalf of the Trust and the Indenture Trustee, (c) that the Transaction Documents constitute the legal, valid and binding agreement of each party thereto, other than Ford, Ford Credit, FCF Corp, FCF LLC and the Trust, enforceable in accordance with their respective terms, (d) the authenticity of all documents submitted to us as originals, (e) the conformity to the original documents of all documents submitted to us as copies, (f) the genuineness of all signatures on all documents submitted to us and (g) the legal capacity of all natural persons.

With respect to the foregoing matters set forth in clauses (a) and (b) of the preceding paragraph as they apply to the Ford, we have relied, with your consent and without independent investigation, on the opinion of Bradley M. Gayton, Secretary and Assistant General Counsel of Ford (the “Gayton Opinion”), addressed to you and dated the date hereof.  With respect to the foregoing matters set forth in clauses (a) and (b) of the preceding paragraph as they apply to Ford Credit, FCF LLC or FCF Corp, we have relied, with your consent and without independent investigation, on the opinion of Susan J. Thomas, Secretary of each of Ford Credit, FCF Corp and FCF LLC and Associate General Counsel, Global Structured Finance of Ford Credit (the “Thomas Opinion”), addressed to you and dated the date hereof.  With respect to the matters set forth in clauses (a) and (b) of the preceding paragraph as they apply to the Trust, we have relied, with your consent and without independent investigation, on the opinions of Richards, Layton &

Based upon the foregoing and subject to the qualifications and assumptions set forth herein, we are of the opinion that:

1.                                      Each of the Basic Documents to which Ford is a party constitutes the legal, valid and binding agreement of, Ford, enforceable against Ford in accordance with its terms.

2.                                      Each of the Basic Documents to which Ford Credit is a party constitutes the legal, valid and binding agreement of, Ford Credit, enforceable against Ford Credit in accordance with its terms.

6.                                      The Notes have been duly authorized by the Trust and, when duly executed and delivered by the Trust, authenticated by the Indenture Trustee and delivered against payment therefor, will constitute the legal, valid and binding obligations of the Trust, enforceable against the Trust in accordance with their terms, and will be entitled to the benefits of the Indenture.

7.                                      The execution and delivery by each of Ford, Ford Credit, FCF Corp, FCF LLC and the Trust of the Transaction Documents to which it is a party, and the compliance by each of Ford, Ford Credit, FCF Corp, FCF LLC and the Trust with the terms and provisions of such agreements, including the issuance of the Notes, will not contravene any provision of any Applicable Law of the State of New York or the State of Delaware or any Applicable Law of the United States of America.

8.                                      No Governmental Approval (other than the filing of UCC financing statements with respect to (x) the sale or transfer of the “Dealer Receivables” (as defined in the Sale and Assignment Agreement) by Ford to Ford Credit pursuant to the Sale and Assignment Agreement, (y) the sale or transfer of the Receivables by Ford Credit to the Depositors pursuant to the Receivables Purchase Agreements and by the Depositors to the Trust pursuant to the Sale and Servicing Agreements and (z) the grant by the Trust of a security interest in such Receivables to the Indenture Trustee pursuant to the Indenture), which has not been obtained or taken and is not in full force and effect, is required to authorize, or is required in connection with, the execution or delivery of the Transaction Documents to which it is a party by Ford, Ford Credit, FCF Corp, FCF LLC and the Trust, or the enforceability of any of the Basic Documents (other than the Trust Agreement) to which it is a party against Ford, Ford Credit, FCF Corp, FCF LLC and the Trust, as applicable.

9.                                      The Registration Statement and any amendments thereto have become effective under the Securities Act and, to the best of our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and not withdrawn, and no proceedings for that purpose have been instituted or threatened and not terminated.

10.                               None of FCF Corp, FCF LLC or the Trust is required to be registered as an “investment company” under the Investment Company Act of 1940, as amended.

11.                               The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, and the Trust Agreement is not required to be qualified under the Trust Indenture Act of 1939, as amended.

12.                               The Notes, the Indenture, the Underwriting Agreement and the other Basic Documents conform in all material respects with their descriptions in the Base Prospectus, the Preliminary Prospectus Supplement and the Final Prospectus Supplement, as applicable.

13.                               The statements contained in the Base Prospectus, the Preliminary Prospectus Supplement and the Final Prospectus Supplement under the heading “ERISA Considerations”, insofar as such statements constitute a summary of law and legal conclusions, and subject to the qualifications therein, have been prepared or reviewed by us and are correct in all material respects.

The opinions expressed herein are subject to the following qualifications and limitations:

(a)                                 The enforceability of the Basic Documents may be limited to the extent that any section thereof relates to the submission to the subject matter jurisdiction of, or

6

the waiver of venue or inconvenient forum objections as they relate to, the United States District Court for the Southern District of New York or the New York State courts.

(b)                                 The enforceability of the Basic Documents referred to in paragraphs 1 through 6 above may be subject to bankruptcy, insolvency, reorganization or other laws relating to or affecting creditors rights generally and to general equity principles.

(c)                                  We express no opinion as to the enforceability of any provision purporting to provide indemnification or contribution relating to matters under federal or state securities laws.

(d)                                 Exculpatory provisions, waivers and provisions regarding arbitration of disputes may be limited on public policy grounds.

(e)                                  We express no opinion as to any consent, approval, authorization, registration or qualification which may be required under state securities or Blue Sky laws.

(f)                                   We express no opinion herein as to the creation, attachment, perfection or priority of any security interests which are purported to be created under the Indenture or the Series 2013-1 Indenture Supplement.

(g)                                  To the extent any opinion relates to the enforceability of the choice of New York law and choice of New York forum provisions of the Transaction Documents, our opinion is rendered in reliance upon New York General Obligation Law §§ 5-1401, 5-1402 (McKinney 2001) and N.Y. C.P.L.R. 327(b) (McKinney 2001) and is subject to the qualification that such enforceability may be limited by public policy considerations of any jurisdiction, other than the courts of the State of New York, in which enforcement of such provisions, or of a judgment upon an agreement containing such provisions, is sought.

(h)                                 We call to your attention that the choice of New York law on the basis of Section 5-1401 of the New York General Obligation Law is only relevant insofar as litigation is brought to enforce the Transaction Documents in the courts of the State of New York, and we have assumed that there is basis for jurisdiction in such courts.

(i)                                     We express no opinion on the enforceability of any provision in a Transaction Document purporting to prohibit, restrict or condition the assignment of rights under such Transaction Document to the extent such restriction on assignability is governed by the Uniform Commercial Code.

We are members of the bar of the State of New York, and we do not express any opinion as to any laws other than the Applicable Laws of the State of New York and the State of Delaware and the federal law of the United States of America.
