         Re:      Capital Auto Receivables, Inc.
                  Registration Statement on Form S-3 (No. 333-93431)
                  Central Originating Lease Trust
                  Registration Statement on Form S-1 (No. 333-93431-01)

                  We have acted as special counsel to Capital Auto Receivables,
Inc., a Delaware corporation (the "Company"), in connection with the
above-referenced Registration Statement (together with the exhibits and any
amendments hereto and the prospectus supplements described therein, the
"Registration Statement"), filed by the Company with the Securities and Exchange
Commission in connection with the registration by the Company of Asset Backed
Securities (the "Securities").

                  Three different base prospectuses and prospectus supplements
are contained in the Registration Statements. One prospectus and related
prospectus supplement, referred to in the Registration Statement as "Version 1"
(the "CARAT Prospectus") pertains to offerings by the Company of Securities
issued by CARAT Trusts (as defined below); the second such prospectus and
related prospectus supplement, referred to in the Registration Statement as
"Version 2" (the "Grantor Trust Prospectus") pertains to offerings by the
Company of Securities issued by Grantor Trusts (as defined below); and the third
such prospectus and related prospectus supplement, referred to in the
Registration Statement as "Version 3" (the "Secured Note Prospectus") pertains
to offerings by the Company of Securities secured by secured notes issued by
Central Originating Lease Trust. This opinion relates only to the CARAT
Prospectus and the Grantor Trust Prospectus and their exhibits contained in the
Registration Statements.

                  As described in the CARAT Prospectus, the Securities issued
pursuant to the CARAT Prospectus and related prospectus supplements (each, a
"CARAT Prospectus Supplement") will be Asset Backed Notes ("CARAT Notes") and
Asset Backed Certificates ("CARAT Certificates") that

will be issued in series. Each series of CARAT Notes and CARAT Certificates will
be issued by a Delaware business trust or common law trust (each, a "CARAT
Trust") to be formed by the Company pursuant to a Trust Agreement (each, a
"CARAT Trust Agreement") between the Company and an Owner Trustee to be
specified in the related CARAT Prospectus Supplement. Each series issued by a
CARAT Trust may include one or more classes of CARAT Notes and one or more
classes of CARAT Certificates. The CARAT Notes of any CARAT Trust will be issued
pursuant to an Indenture (each, a "CARAT Indenture") by and between such CARAT
Trust and an Indenture Trustee to be specified in the related CARAT Prospectus
Supplement and a Trust Sale and Servicing Agreement by and among such CARAT
Trust, the Company and General Motors Acceptance Corporation, as servicer (each,
a "CARAT Trust Sale and Servicing Agreement"). The CARAT Certificates of any
CARAT Trust will be issued pursuant to a CARAT Trust Agreement.

                  As described in the Grantor Trust Prospectus, the Securities
issued pursuant to the Grantor Trust Prospectus and related prospectus
supplements will be Asset Backed Certificates, Class A (the "Grantor Trust
Certificates") to be issued in series, each series to be issued by a grantor
trust to be formed by the Company (each, a "Grantor Trust"). Each series will be
issued pursuant to a Pooling and Servicing Agreement among the Company, as
Seller, General Motors Acceptance Corporation, as Servicer, and a Trustee to be
specified in the related Grantor Trust Prospectus Supplement (the "Trustee")
(each, a "Grantor Trust Pooling and Servicing Agreement").

                  We are generally familiar with the proceedings required to be
taken in connection with the proposed authorization, issuance and sale of the
CARAT Notes, CARAT Certificates and Grantor Trust Certificates, and in order to
express the opinion hereinafter stated, we have examined copies of the
Registration Statement and, in each case as filed as an exhibit to or
incorporated by reference in the Registration Statement, (i) the form of CARAT
Indenture, (ii) the form of CARAT Trust Agreement (including the form of
Certificate of Trust to be filed pursuant to the Delaware Business Trust Act
included as an exhibit thereto (a "CARAT Trust Certificate")), (iii) the form of
CARAT Trust Sale and Servicing Agreement, (iv) the form of CARAT Pooling and
Servicing Agreement between General Motors Acceptance Corporation and the
Company and (v) the form of Administration Agreement among the related CARAT
Trust, the related Indenture Trustee and General Motors Acceptance Corporation,
as administrator (collectively, the "CARAT Operative Documents"). We also have
examined (i) the form of Grantor Trust Pooling and Servicing Agreement, (ii) the
form of the Grantor Trust Certificate and (iii) the form of Purchase Agreement
between General Motors Acceptance Corporation and the Company, in each case as
filed as an exhibit to the Registration Statement (collectively, the "Grantor
Trust Operative Documents"). We

have examined such other documents and such matters of law, and we have
satisfied ourselves as to such matters of fact, as we have considered relevant
for purposes of this opinion.

                  On the basis of the foregoing and on the basis of our
examination of the Company's Amended and Restated Certificate of Incorporation
and Amended and Restated By-laws and a review of a Certificate of the Secretary
of State of the State of Delaware as to the good standing of the Company, it is
our opinion that:

         standing under the laws of the State of Delaware;

                  (b) With respect to the CARAT Notes and CARAT Certificates of

         the Company's Board of Directors, (iii) the CARAT Operative Documents
         relating thereto have each been duly completed, executed and delivered
         by the parties thereto substantially in the form we have examined, duly
         reflecting the terms established as described above, (iv) the CARAT
         Trust Certificate for the related CARAT Trust has been duly executed by
         the Owner Trustee and timely filed with the Secretary of State of the
         State of Delaware, (v) the related CARAT Indenture has been duly
         qualified under the Trust Indenture Act of 1939, as amended, and (vi)
         such CARAT Notes and CARAT Certificates have been duly executed and
         issued by such CARAT Trust and authenticated by the Indenture Trustee
         or the Owner Trustee, as appropriate, and sold by the Company, all in
         accordance with the terms and conditions of the related CARAT Operative
         Documents and in the manner described in the Registration Statement,
         such CARAT Notes and CARAT Certificates will have been duly authorized
         by all necessary action of such CARAT Trust and will have been legally
         issued and will be enforceable in accordance with their terms and
         entitled to the benefits of the related CARAT Operative Documents,
         except as the same may be limited by Title 11 of the United States Code
         or other bankruptcy, insolvency, reorganization, moratorium, or other
         laws relating to or affecting the enforcement of creditors' rights or
         the relief of debtors, as may be in effect from time to time, or by
         general principles of equity; and

                  (c) With respect to the Grantor Trust Certificates of any
         series, when, as and if (i) the Registration Statement becomes
         effective pursuant to the provisions of the Securities Act of 1933, as
         amended, (ii) the principal balance, price, interest rate and other
         principal terms of such Grantor Trust Certificates have been duly

         above, and (iv) such Grantor Trust Certificates have been duly executed

         the Registration Statement, such Grantor Trust Certificates will have
         been duly authorized by all necessary corporate action of the Company
         and will have been legally issued and will be enforceable in accordance
         with their terms and entitled to the benefits of the related Grantor
         Trust Pooling and Servicing Agreement, except as the same may be
         limited by Title 11 of the United States Code or other bankruptcy,
         insolvency, reorganization, moratorium, or other laws relating to or
         affecting the enforcement of creditors' rights or the relief of
         debtors, as may be in effect from time to time, or by general
         principles of equity.

                  We do not find it necessary for the purposes of this opinion,
and accordingly we do not purport to cover herein, the application of securities
or "Blue Sky" laws of the various states to the offer or sale of the CARAT
Notes, CARAT Certificates and Grantor Trust Certificates.
