    RE: Form of Confirmation of Primary Swap Relating to the Class A-1 Notes


Dear Ladies and Gentlemen:

     The purpose of this letter agreement is to confirm the terms and conditions
of the Swap Transaction (the "Primary Swap") entered into between Citibank, N.A.
(the "Counterparty") and Capital Auto Receivables Asset Trust 2002-5 (the
"Trust") as of the Trade Date listed below (the "Transaction"). This letter
constitutes a "Confirmation" as referred to in the Primary ISDA Agreement
specified below.

1.   The definitions and provisions contained in the 2000 ISDA Definitions (the
     "Definitions"), as published by the International Swaps and Derivatives
     Association, Inc. ("ISDA"), are incorporated into this Confirmation. In the
     event of any inconsistency between those definitions and provisions and
     this Confirmation, this Confirmation will govern. The parties agree that
     this transaction is a Transaction under the ISDA Master Agreement of the
     parties dated as of November 13, 2002. The agreement is comprised of the
     printed form of such agreement as published by ISDA, as supplemented and
     modified by a Schedule (the "Primary ISDA Agreement").

     This Confirmation constitutes a binding agreement between you and us and
     will supplement, form a part of, and be subject to the Primary ISDA
     Agreement described above as amended and supplemented from time to time.

     The Counterparty and the Trust acknowledge that this Transaction relates to
     the Class A-1 Floating Rate Asset Backed Notes (the "Reference Notes")
     issued by the Trust for value pursuant to and subject to the Indenture.

     Capitalized terms used and not otherwise defined herein, in the Primary
     ISDA Agreement or in the Definitions shall have the meanings assigned to
     them in Exhibit A or Exhibit B hereto, as applicable.

     All references to "dollars" or to "$" shall be references to amounts in
     United States Dollars.

2.   The terms of the particular Transaction to which this Confirmation relates
     are as follows:

     Type of Transaction: Interest Rate Swap.

     Notional Amount: $485,000,000.00 with respect to the initial Calculation
     Period. The Notional Amount with respect to each Calculation Period
     thereafter shall be equal to the Reference Note Balance as of the close of
     business on the Distribution Date at the beginning of the relevant
     Calculation Period (as set forth in the Calculation Statement (defined
     below) delivered by the Trust to the Counterparty on or prior to the
     Determination Date relating to such Calculation Period pursuant to Section
     3 below).

     Trade Date: November 5, 2002.

     Effective Date: November 13, 2002.



     Termination Date: The earlier of the close of business on (i) January 15,

     Fixed Amounts:

          Fixed Rate Payer: The Trust.

          Fixed Rate Payer Period End Dates: The 15th calendar day of each

          with, in each case, subject to adjustment in accordance with the
          Following Business Day Convention.

          Fixed Rate Payer Payment Date: One Business Day prior to each
          Distribution Date.

          Date.

     agent for and on behalf of the Trust.

     Default Rate: For any United States Dollar payments, the rate determined
     under the option entitled "USD Federal Funds - H.15" plus 1% using daily
     Reset Dates. The Default Rate will be applied on the basis of Compounding
     as if the overdue amount were a Notional Amount and using daily Compounding
     Dates, and interest will accrue and be payable before as well as after
     judgment.

3.   Calculations and Notifications: On or before each Determination Date, the
     Calculation Agent shall determine the Fixed Amount due to the Counterparty
     on the next succeeding Fixed Rate Payer Payment Date and the Floating
     Amount due to the Trust on the next succeeding Floating Rate Payer Payment
     Date and the Calculation Agent shall notify the Counterparty in writing of
     both (i) the Floating Rate and (ii) the amount of such payment.

                                        2



     In addition, on each Determination Date the Trust shall deliver to the
     Counterparty (by facsimile with hard copy to follow) a statement (the
     "Calculation Statement") setting forth with respect to the close of
     business on the immediately preceding Distribution Date the Reference Note
     Balance as of such Distribution Date.

     The Trust will give the Counterparty prompt written notice of any Default
     under the Indenture.

4.   Credit Downgrade: In the event that the Joint Probability is reduced below
     AA- in the case of S&P or Aa3, in the case of Moody's, the Offsetting
     Counterparty shall promptly notify the Trust (and any permitted assignee or
     transferee of the Trust) and the Counterparty of such event and (unless,
     within thirty (30) days after such reduction, the applicable Rating Agency
     has reconfirmed the ratings of the Reference Notes and the Other Securities
     that were in effect immediately prior to such reduction) the Counterparty
     shall within thirty (30) days of receipt of notice of such reduction, with
     the prior written confirmation of the applicable Rating Agency that such
     arrangement will not result in the reduction of the rating of any of the
     Reference Notes or the Other Securities existing immediately prior to the
     reduction of the applicable Joint Probability, either:

          (1) (x) obtain a substitute swap provider (the "Substitute Swap
          Provider") acceptable to the Trust (such acceptance not to be
          unreasonably withheld) and replace this Transaction with a swap
          transaction on substantially similar terms or with such other
          amendments as consented to in writing by the Trust (which consent
          shall not be unreasonably withheld), provided such replacement would
          result in an S&P Joint Probability of at least AA- and a Moody's Joint
          Probability of at least Aa3, except that such Substitute Swap Provider
          shall thenceforth be the "Counterparty" hereunder; or (y) replace,
          with the consent of the then current Offsetting Counterparty, the swap
          transaction with the then current Offsetting Counterparty with a swap
          transaction with a replacement Offsetting Counterparty on terms
          approved by S&P and Moody's or enter into a swap transaction with
          another party such that such party shall be acting as an intermediary
          between the Counterparty and the then current Offsetting Counterparty
          (such replacement or intermediary being the "Replacement Offsetting
          Counterparty"); or

          (2) enter into an ISDA Credit Support Annex with the Trust mutually
          acceptable to the Trust and the Counterparty; or

          (3) enter into such other credit support arrangements to assure
          performance by the Counterparty of its obligations under this
          Transaction.

     Notwithstanding the foregoing, in the event that the Joint Probability is
     reduced below A- in the case of S&P, or A3, in the case of Moody's, then
     the Offsetting Counterparty shall promptly notify the Trust (and any
     permitted assignee or transferee of the Trust) and the Counterparty of such
     event and (unless, within thirty (30) days after such reduction the
     applicable Rating Agency has reconfirmed the ratings of the Reference Notes
     and the Other Securities that were in effect immediately prior to such
     reduction) the Counterparty shall within thirty (30) days of receipt of
     notice of such reduction, with the prior written confirmation of the
     applicable Rating Agency that such arrangement will not result in the
     reduction of the rating of any of the Reference Notes or the Other
     Securities existing immediately prior to the reduction of the applicable
     Joint Probability as a direct result of the reduction of such Joint
     Probability, obtain a Substitute Swap Provider acceptable to the Trust
     (such acceptance not to be unreasonably withheld) and replace this
     Transaction with a swap transaction on substantially similar terms or with
     such other amendments as consented to in writing by the Trust (which
     consent shall not be unreasonably withheld) provided such replacement would
     result in an S&P Joint Probability of at

                                        3



     least AA- or a Moody's Joint Probability of Aa3 except that such Substitute
     Swap Provider shall thenceforth be the "Counterparty" hereunder.

     Upon any replacement of this Transaction with a swap transaction with a
     Substitute Swap Provider, this Transaction shall terminate without any
     payment by either party hereto and any and all collateral posted by the
     Counterparty shall be returned to it within three (3) Business Days and any
     other form of collateral arrangement (including letters of credit, surety
     bond or other guarantee) provided by or on behalf of the Counterparty shall
     terminate.

     In the event that the Counterparty fails to satisfy its obligations set
     forth above in this Section 4, the Trust or any permitted assignee or
     transferee of the Trust shall have the option, exercisable in its
     discretion and with regard to the interests of the Noteholders, within ten
     (10) Business Days following the date of expiry of the thirty (30) day
     period after the date of receipt of notice of the reduction (unless, within
     thirty (30) days of receipt of notice of such reduction, the applicable
     Rating Agency has reconfirmed the rating of the Reference Notes that was in
     effect immediately prior to such reduction), to designate (in writing) an
     Early Termination Date on the basis that such failure shall be treated as a
     Termination Event with the Counterparty as the Affected Party. For the
     avoidance of doubt, the Counterparty and the Trust acknowledge and agree
     that any such failure shall not constitute an Event of Default.

Primary Confirmation of A-1 Interest Rate Swap



                                    EXHIBIT A

The following terms shall have the following meanings in this Confirmation:

     "Determination Date": the tenth (10th) day of each calendar month, or if
such tenth (10th) day is not a Business Day, the next succeeding Business Day.

     "Distribution Date": the fifteenth (15th) day of each succeeding calendar
month following the Effective Date or, if such fifteenth (15th) day is not a
Business Day, the next such succeeding Business Day, commencing on the first day
following the Effective Date.

     "Indenture": the Indenture, dated as of the date hereof between the Trust
and the Indenture Trustee, as amended and supplemented from time to time in
accordance with its terms.

     "Indenture Trustee": Bank One, National Association, not in its individual
capacity but solely as trustee under the Indenture, or any successor trustee
under the Indenture.

     "LIBOR": with respect to each Floating Rate Payer Payment Date, the rate
for deposits in U.S. Dollars for a period of one month which appears on the
Telerate Service Page 3750 as of 11:00 a.m., London time, on the day that is two
LIBOR Business Days prior to the Distribution Date (or, in the case of the
initial Floating Rate Payer Payment Date, two LIBOR Business Days prior to
Closing Date) preceding such Floating Rate Payer Payment Date. If the rate does
not appear on that date on the Telerate Service Page 3750 (or any other page as
may replace that page on that service, or if that service is no longer offered,
any other service for displaying LIBOR or comparable rates as may be selected by
the Indenture Trustee after consultation with the Seller), then LIBOR will be
the Reference Bank Rate.

     "LIBOR Business Day": any day other than a Saturday, Sunday or any other
day on which banks in London are required or authorized to be closed.

     "Other Securities": Class A-2a, Class A-2b, Class A-3a, Class A-3b, Class
A-4 Notes and Certificates issued by the Trust.

     "Reference Bank Rate": for any Floating Rate Payer Payment Date, the per
annum rate determined on the basis of the rates at which deposits in U.S.
Dollars are offered by the reference banks (which will be four major banks that
are engaged in transactions in the London interbank market, selected by the
Calculation Agent) as of 11:00 a.m., London time, on the day that is two LIBOR
Business Days prior to the Distribution Date preceding such Floating Rate Payer
Payment Date to prime banks in the London interbank market for a period of one
month, in amounts approximately equal to the principal amount of the Reference
Notes then outstanding. The Calculation Agent will request the principal London
office of each of the reference banks to provide a quotation of its rate. If at
least two quotations are provided, the rate will be the arithmetic mean of the
quotations, rounded upwards to the nearest one-sixteenth of one percent. If on
that date fewer than two quotations are provided as requested, the rate will be
the arithmetic mean, rounded upwards to the nearest one-sixteenth of one
percent, of the rates quoted by one or more major banks in New York City,
selected by the Calculation Agent, as of 11:00 a.m., New York City time, on that
date to leading European banks for United States dollar deposits for a period of
one month in amounts approximately equal to the principal amount of the
Reference Notes then outstanding. If no quotation can be obtained, then LIBOR
will be the rate for the prior Floating Rate Payer Payment Date.

     "Reference Note Balance": as of the Effective Date, $485,000,000.00 and,
with respect to each Distribution Date thereafter, the aggregate principal
balance of any and all outstanding Reference Notes.

                                      A - 1



     "Seller": Capital Auto Receivables, Inc., which has executed the Trust Sale
and Servicing Agreement as the Seller, or its successor in interest pursuant to
Section 3.03 of the Trust Sale and Servicing Agreement.

     "Trust Sale and Servicing Agreement": the Trust Sale and Servicing
Agreement, dated as of the date hereof between the Seller, General Motors
Acceptance Corporation, as Servicer, and the Trust, as amended, modified and
supplemented from time to time in accordance with its terms.

                                      A - 2



                                    EXHIBIT B

     "Contingent Party": the Offsetting Counterparty or the Replacement
Offsetting Counterparty, as applicable.

     "Fallback Swap Transaction": the swap transaction entered into by the Trust
and Offsetting Counterparty relating to the Class A-1 Notes.

     "Joint Probability": the Moody's Joint Probability or the S&P Joint
Probability, as applicable.

     "Moody's": Moody's Investors Service, Inc. and its successors.

     "Moody's Joint Probability" means the joint probability determined by
Moody's of the long-term likelihood of payment under this interest rate swap
determined by locating the intersection of the long-term unsecured debt ratings
of the Primary Party and the Contingent Party on the table below headed "Implied
Joint Support Rating for Medium Correlation Case" (except that, for any pairing
other than the initial Primary Party with the initial Contingent Party, the
table below to be used shall be the table headed "Implied Joint Support Rating
for Low Correlation Case" or the table headed "Implied Joint Support Rating for
High Correlation Case" if so specified by Moody's within five days after Moody's
has received notice of a potential pairing of a Primary Party with a Contingent
Party).

Notwithstanding the foregoing, in the event that under the Triparty Agreement
the Offsetting Counterparty has acceded to the rights of the Counterparty and no
swap transaction has been effected with an additional contingent counterparty or
replacement swap counterparty under the circumstances contemplated by Section

                                      B - 2



2.02 of the Triparty Agreement, then the term "Moody's Joint Probability" shall
refer to the Offsetting Counterparty's long term senior unsecured credit rating
assigned by Moody's (and, for avoidance of doubt, the obligations of the
Counterparty specified in Section 4 of this Confirmation shall constitute
obligations of the Offsetting Counterparty).

     "Offsetting Counterparty" means General Motors Acceptance Corporation or
any successor thereto ("GMAC") under the Fallback Swap Transactions entered into
between the Trust and GMAC.

     "Primary Party": the Counterparty, unless a Substitute Swap Provider has
been obtained, in which case it shall be the Substitute Swap Provider or, if
applicable, a guarantor thereof.

     "Rating Agency": each of S&P and Moody's.

     "S&P": Standard & Poor's Ratings Services and its successors.

     "S&P Joint Probability" means the joint probability determined by S&P of
the long-term likelihood of payment under the interest rate swap determined by
locating the intersection of the Counterparty's long term senior unsecured debt
rating and the Offsetting Counterparty's long-term senior unsecured debt rating
in the following table:

Notwithstanding the foregoing, (i) in the event that the long-term senior
unsecured debt rating of either the Primary Party or the Contingent Party is
rated below BBB- by S&P, then the S&P Joint Probability shall be the higher of
the then current long-term senior unsecured debt rating of the Primary Party and
the Contingent Party and (ii) in the event that under the Triparty Agreement the
Offsetting Counterparty has acceded to the rights of the Counterparty and no
swap transaction has been effected with an additional contingent counterparty or
replacement swap counterparty under the circumstances contemplated by Section
2.02 of the Triparty Agreement, then the term "S&P Joint Probability" shall
refer to the Offsetting Counterparty's long-term senior unsecured credit rating
assigned by S&P (and, for the avoidance of doubt, the obligations of the
Counterparty specified in Section 4 of this Confirmation shall constitute
obligations of the Offsetting Counterparty).

     "Triparty Agreement": the Triparty Contingent Assignment Agreement dated as
of the Effective Date among the Trust, the Offsetting Counterparty and the
Counterparty.
