         Re: Federal Income Tax Consequences

         We are issuing this opinion letter in our capacity as special counsel
to Capital Auto Receivables, Inc. (the "Seller"), and General Motors Acceptance
Corporation ("GMAC") in connection with:

              (1)   the issuance of $840,800,000 aggregate principal amount of
         Class A-2a Asset Backed Notes (the "Class A-2a Notes") the issuance of
         $281,000,000 aggregate principal amount of Class A-2b Asset Backed
         Notes (the "Class A-2b Notes"), $680,100,000 aggregate principal amount
         of Class A-3 Asset Backed Notes (the "Class A-3 Notes") and
         $589,900,000 aggregate principal amount of Class A-4 Asset Backed Notes
         (the "Class A-4 Notes" and together with the Class A-2a Notes, the
         Class A-2b Notes, and the Class A-3 Notes, the "Notes") by Capital Auto
         Receivables Asset Trust 2002-4 (the "Trust") pursuant to an Indenture
         (the "Indenture"), between the Trust and Bank One, National
         Association, as Indenture Trustee (the "Indenture Trustee"); and

              (2)   the issuance of $92,560,897.59 aggregate principal amount
         of Asset Backed Certificates (the "Certificates") by the Trust,
         pursuant to a Trust Agreement (the "Original Trust Agreement"), dated
         as of October 1, 2002, to be amended and restated as of the Issuance
         Date (the "Trust Agreement"), between the Seller and Deutsche Bank
         Trust Company Delaware, as Owner Trustee (the "Owner Trustee").

         The Trust intends to issue the Notes and the Certificates on or about
October 10, 2002 (the "Issuance Date"). In arriving at the opinions expressed
below, among other things, we have examined and relied, to the extent we deem
proper, on the following documents:

              (i) a copy of the registration statement filed with the Securities
              and Exchange Commission (the "Commission") pursuant to Rule 415
              under the Securities Act of 1933, as amended (the "Act"), on Form
              S-3 (File No. 333-75464) on January 28, 2002 with respect to
              asset-backed notes and certificates, including the Notes, to be

              issued and sold in series from time to time, in the form in which
              it became effective, including the exhibits thereto;

              (ii)  a copy of a form of prospectus supplement relating to the
              Notes substantially in the form to be filed with the Commission
              pursuant to Rules 424(b)(5) and 424(c) under the Act (the
              "Prospectus Supplement") and the prospectus, dated July 29, 2002,
              relating thereto (the "Base Prospectus" and, together with the
              Prospectus Supplement, the "Prospectus");

              (iii) the Original Trust Agreement and a form of the Trust
              Agreement;

              (iv)  a form of the Trust Sale and Servicing Agreement, among the
              Seller, GMAC, as Servicer, and the Trust (the "Trust Sale and
              Servicing Agreement");

              (v)   a form of the Indenture;

              (vi)  a form of the Pooling and Servicing Agreement (the "Pooling
              and Servicing Agreement"), between GMAC and the Seller; and

              (vii) such other documents as we have deemed necessary for the
              expression of the opinions contained herein (collectively, the
              documents described in clauses (iii) through (vi) are referred to
              herein as the "Transaction Documents").

         In arriving at the opinion expressed below, we have examined and
relied, to the extent we deemed proper, on the Transaction Documents. In our
examination, we have assumed that the Transaction Documents will be executed in
the form submitted to us on or before the Issuance Date, and we have assumed the
enforceability of all Transaction Documents. We have also assumed, without
independent verification, that the facts and representations and warranties in
the documents upon which we relied are true and correct, and that the
transactions contemplated by such documents will be consummated strictly in
accordance with their terms.

         In rendering our opinion, we have also considered and relied upon the
Internal Revenue Code of 1986, as amended (the "Code"), administrative rulings,
judicial decisions, regulations, and such other authorities (including Treasury
regulations) as we have deemed appropriate, all as in effect on the date hereof
and all of which are subject to change or different interpretation. However, we
will not seek a tax ruling from the Internal Revenue Service (the "IRS") with
respect to any of the matters discussed herein. Moreover, the statutory
provisions, regulations, interpretations and other authorities upon which our
opinion is based are subject to change, and such changes could apply
retroactively. In addition, there can be no assurance that positions contrary to
those stated in our opinion will not be taken by the IRS. Our opinion is in no
way binding on the IRS or any court, and it is possible that the IRS or a court
could, when presented with these facts, reach a different conclusion. We express
no opinion herein as to any laws other than federal law of the United States of
America. In rendering such opinions, we have assumed

that the Trust will be operated in accordance with the terms of the Trust
Agreement, the Trust Sale and Servicing Agreement, the Pooling and Servicing
Agreement and the Indenture.

         Based on and subject to the foregoing, we are of the opinion that under
the existing tax laws of the United States of America, although no transaction
closely comparable to those contemplated herein has been the subject of any
Treasury regulation, revenue ruling, or judicial decision, for United States
federal income tax purposes:

              (i)    the statements in the Base Prospectus under the caption
              "Federal Income Tax Consequences" and in the Prospectus Supplement
              under the caption "Federal Income Tax Consequences", to the extent
              that they constitute matters of law or legal conclusions, have
              been prepared or reviewed by us and are correct in all material
              respects;

              (ii)   the Notes will be characterized as indebtedness; and

              (iii)  the Trust will not be taxable as an association or publicly
              traded partnership taxable as a corporation, but instead will be
              classified as a partnership.

         Except for the opinions expressed above, we express no opinion as to
any other tax consequences of the transaction to any party under federal, state,
local, or foreign laws. In addition, we express no opinion as to the laws of any
jurisdiction other than the federal laws of the United States of America to the
extent specifically referred to herein. This letter is limited to the specific
issues addressed herein and the opinions rendered above are limited in all
respects to laws and facts existing on the date hereof. By rendering these
opinions, we do not undertake to advise you with respect to any other matter or
of any change in such laws or facts or in the interpretations of such laws which
may occur after the date hereof or as to any future action that may become
necessary to maintain the character of the Notes as indebtedness or the Trust as
disregarded as an entity separate from its owner for federal income tax
purposes.

         We hereby consent to the filing of this opinion with Form 8-K and to
the reference to our firm in the Base Prospectus under the captions "Federal
Income Tax Consequences" and "Legal Opinions" and in the Prospectus Supplement
in the Summary under the captions "Tax Status" and "Federal Income Tax
Consequences." In giving this consent, we do not thereby admit that we come
within the category of persons whose consent is required under Section 7 of the
Act or the rules and regulations of the Securities and Exchange Commission
thereunder.

                                    Very truly yours,
