     THIS PURCHASE AGREEMENT is made and entered into as of September 23, 2003
(as amended from time to time, this "Agreement") by CAPITAL ONE AUTO FINANCE,

set forth in this Agreement.

     NOW, THEREFORE, in consideration of the premises and the mutual agreements

                                   ARTICLE I

                              DEFINITIONS AND USAGE

context may otherwise require, capitalized terms used but not otherwise defined
herein are defined in Appendix A to the Sale and Servicing Agreement dated as of
the date hereof (as from time to time amended, supplemented or otherwise

Prime Auto Receivables Trust 2003-2, COAF, as servicer, the Purchaser, as
seller, and JPMorgan Chase Bank, as indenture trustee, which also contains rules

     SECTION 1.2 Other Interpretive Provisions. For purposes of this Agreement,

defined in this Agreement, and accounting terms partly defined in this Agreement
to the extent not defined, shall have the respective meanings given to them

                                   ARTICLE II

                                    PURCHASE

     SECTION 2.1 Agreement to Sell and Contribute on the Closing Date. On the
terms and subject to the conditions set forth in this Agreement, COAF does
hereby irrevocably sell, transfer, assign and otherwise convey to the Purchaser
without recourse (subject to the obligations herein) on the Closing Date all of
its right, title and interest in, to and under the Receivables, the Collections
after the Initial Cut-Off Date and the Related Security relating thereto,
together with all of COAF's rights under the Sale Agreement, whether now owned
or hereafter acquired, described in an Assignment in the form of Exhibit A
delivered on the Closing Date, and its rights under the Sale Agreement
(collectively, the "Initial Purchased Assets"), which sale shall be effective as
of the Initial Cut-Off Date. The sale, transfer, assignment and conveyance made
hereunder does not constitute and is not intended to result in an assumption by
the Purchaser of any obligation of COAF or any Originator to the Obligors, the
Dealers or any other Person in connection with the Receivables or the other
assets and properties conveyed hereunder or any agreement, document or
instrument related thereto.

     SECTION 2.2 Agreement to Sell and Contribute on the Funding Dates. On the
terms and subject to the conditions set forth in this Agreement, COAF does
hereby sell, transfer, assign and otherwise convey to the Purchaser on each
Funding Date all of its right, title and interest in, to and under the
Receivables, and the Collections after the related Subsequent Cut-Off Date and
the Related Security relating thereto, whether now owned or hereafter acquired,
described in an Assignment in the form of Exhibit A delivered on such Funding
Date (collectively, the "Subsequent Purchased Assets" and, together with the
Initial Purchased Assets, all of COAF's rights under the Sale Agreement and all
proceeds of the foregoing, the "Purchased Assets"). The sale, transfer,
assignment and conveyance made hereunder does not constitute and is not intended
to result in an assumption by the Purchaser of any obligation of COAF or any
Originator to the Obligors, the Dealers or any other Person in connection with
the Receivables or the other assets and properties conveyed hereunder or any
agreement, document or instrument related thereto.

     SECTION 2.3 Consideration and Payment. In consideration of the sale of the
Initial Purchased Assets sold to the Purchaser on the Closing Date, the
Purchaser shall pay to COAF on such date an amount equal to $874,060,679.67,
representing the estimated fair market value of the Initial Purchased Assets on
the Closing Date.

     SECTION 2.4 Consideration and Payment for the Subsequent Purchased Assets.
In consideration of the sale of the Subsequent Purchased Assets sold to the
Purchaser on each Funding Date, the Purchaser shall pay to COAF on such date an
amount equal to the estimated fair market value of the related Subsequent
Purchased Assets on such Funding Date (the "Purchase Price").

                                   ARTICLE III

                    REPRESENTATIONS, WARRANTIES AND COVENANTS

     SECTION 3.1 Representations and Warranties of COAF. COAF makes the
following representations and warranties as of the Closing Date and as of each
Funding Date on which the Purchaser will be deemed to have relied in acquiring
the Purchased Assets. The representations and warranties speak as of the
execution and delivery of this Agreement and will survive the conveyance of the
Purchased Assets to the Purchaser, the conveyance of the Transferred Assets to
the Issuer pursuant to the Sale and Servicing Agreement and the pledge thereof
by the Issuer to the Indenture Trustee pursuant to the Indenture:

     (a) Existence and Power. COAF is a corporation validly existing and in good
standing under the laws of its state of organization and has, in all material
respects, full power and authority to own its assets and operate its business as
presently owned or operated, and to execute, deliver and perform its obligations
under the Transaction Documents to which it is a party or affect the
enforceability or collectibility of the Receivables or any other part of the
Purchased Assets. COAF has obtained all necessary licenses and approvals in each
jurisdiction where the failure to do so would materially and adversely affect
the ability of COAF to perform its obligations under the Transaction Documents
or affect the enforceability or collectibility of the Receivables or any other
part of the Purchased Assets.

     (b) Authorization and No Contravention. The execution, delivery and
performance by COAF of the Transaction Documents to which it is a party have
been duly authorized by all necessary action on the part of COAF and do not
contravene or constitute a default under (i) any applicable law, rule or
regulation, (ii) its organizational documents or (iii) any material indenture or
material agreement or instrument to which COAF is a party or by which its
properties are bound (other than violations of such laws, rules, regulations,
indentures or agreements which do not affect the legality, validity or
enforceability of any of such agreements and which, individually or in the
aggregate, would not materially and adversely affect the transactions
contemplated by, or COAF's ability to perform its obligations under, the
Transaction Documents).

     (c) No Consent Required. No approval or authorization by, or filing with,
any Governmental Authority is required in connection with the execution,
delivery and performance by COAF of any Transaction Document other than (i) UCC
filings, (ii) approvals and authorizations that have previously been obtained
and filings that have previously been made and (iii) approval, authorizations or
filings which, if not obtained or made, would not have a material adverse effect
on the enforceability or collectibility of the Receivables or any other part of
the Purchased Assets or would materially and adversely affect the ability of
COAF to perform its obligations under the Transaction Documents.

     (d) Binding Effect. Each Transaction Document to which COAF is a party
constitutes the legal, valid and binding obligation of COAF enforceable against
COAF in accordance with its terms, except as such enforceability may be limited
by applicable bankruptcy, insolvency, reorganization, moratorium, receivership,
conservatorship or other

                                                              Purchase Agreement

                                       -3-

<PAGE>

similar laws affecting creditors' rights generally and, if applicable, the
rights of creditors of limited liability companies from time to time in effect
or by general principles of equity.

     (e) No Proceedings. There are no actions, suits or proceedings pending or,
to the knowledge of COAF, threatened against COAF before or by any Governmental
Authority that (i) assert the invalidity or unenforceability of this Agreement
or any of the other Transaction Documents, (ii) seek to prevent the issuance of
the Notes or the consummation of any of the transactions contemplated by this
Agreement or any of the other Transaction Documents, (iii) seek any
determination or ruling that would materially and adversely affect the
performance by COAF of its obligations under this Agreement or any of the other
Transaction Documents or have a material adverse effect on the Noteholders, or
(iv) relate to COAF that would materially and adversely affect the federal or
Applicable Tax State income, excise, franchise or similar tax attributes of the
Notes.

     (f) Lien Filings. COAF is not aware of any material judgment, ERISA or tax
lien filings against COAF.

     SECTION 3.2 Representations and Warranties of COAF as to each Receivable.
On the date hereof or on each Funding Date, as the case may be, the COAF hereby
makes the representations and warranties set forth on Schedule I to the Sale and
Servicing Agreement as to the Receivables sold, transferred, assigned and
otherwise conveyed to the Purchaser under this Agreement on which such
representations and warranties the Purchaser relies in acquiring the
Receivables. Such representations and warranties as to each Receivable relate to
the characteristics of such Receivable as of the applicable Cut-Off Date for
such Receivable (unless Scheduled I to the Sale and Servicing Agreement
specifically identifies a different date as applying to a particular
representation or warranty), but shall survive the sale of such Receivables to
the Issuer under the Sale and Servicing Agreement, and the Grant of the
Receivables by the Issuer to the Indenture Trustee pursuant to the Indenture.
Notwithstanding any statement to the contrary contained herein or in any other
Transaction Document, COAF shall not be required to notify any insurer with
respect to any Insurance Policy obtained by an Obligor or to notify any Dealer
about any aspect of the transaction contemplated by the Transaction Documents.

     SECTION 3.3 Repurchase upon Breach. Upon discovery by or notice to the
Purchaser or COAF of a breach of any of the representations and warranties
described in Section 3.2 at the time such representations and warranties were
made which materially and adversely affects the interests of the Issuer or the
Noteholders, the party discovering such breach or receiving such notice shall
give prompt written notice thereof to the other party; provided, that the
failure to give such notice shall not affect any obligation of COAF hereunder.
If COAF does not correct or cure such breach prior to the end of the Collection
Period which includes the 60th day (or, if the Seller elects, an earlier date)
after the date that COAF became aware or was notified of such breach, then COAF
shall purchase any Receivable affected by such breach which materially and
adversely affects the interests of the Issuer and the Noteholders from the
Purchaser on the Payment Date following the end of such Collection Period. Any
such breach or failure will not be deemed to have a material and adverse effect
if such breach or failure does not affect the ability of the Purchaser (or its
assignee) to receive and retain timely payment in full on such Receivable. Any
such purchase by COAF shall be at a price equal to the Repurchase Price. In

                                                              Purchase Agreement

                                       -4-

<PAGE>

consideration for such repurchase, COAF shall make (or shall cause to be made) a
payment to the Purchaser equal to the Repurchase Price by depositing such amount
into the Collection Account prior to noon, New York City time on such Payment
Date. Upon payment of such Repurchase Price by COAF, the Purchaser shall release
and shall execute and deliver such instruments of release, transfer or
assignment, in each case without recourse or representation, as shall be
reasonably necessary to vest in COAF or its designee any Receivable repurchased
pursuant hereto. It is understood and agreed that the obligation of COAF to
purchase any Receivable as described above shall constitute the sole remedy
respecting such breach available to the Purchaser.

     SECTION 3.4 Protection of Title.

     (a) COAF shall authorize and file such financing statements and cause to be
authorized and filed such continuation and other statements, all in such manner
and in such places as may be required by law fully to preserve, maintain and
protect the interest of the Purchaser under this Agreement in the Purchased
Assets. COAF shall deliver (or cause to be delivered) to the Purchaser
file-stamped copies of, or filing receipts for, any document filed as provided
above, as soon as available following such filing.

     (b) COAF shall not change its name, identity, corporate structure or
jurisdiction of organization in any manner that would make any financing
statement or continuation statement filed by COAF in accordance with paragraph
(a) above "seriously misleading" within the meaning of Sections 9-506, 9-507 or
9-508 of the UCC, unless it shall have given the Purchaser at least five days'
prior written notice thereof and, to the extent necessary, shall have promptly
filed amendments to previously filed financing statements or continuation
statements described in paragraph (a) above.

     (c) COAF shall give the Purchaser at least five days' prior written notice
of any change of location of COAF for purposes of Section 9-307 of the UCC and
shall have taken all action prior to making such change (or shall have made
arrangements to take such action substantially simultaneously with such change,
if it is not possible to take such action in advance) reasonably necessary or
advisable in the opinion of the Purchaser to amend all previously filed
financing statements or continuation statements described in paragraph (a)
above.

     (d) COAF shall maintain (or shall cause its Sub-Servicer to maintain)
accounts and records as to each Receivable accurately and in sufficient detail
to permit (i) the reader thereof to know at any time the status of such
Receivable, including payments and recoveries made and payment owing (and the
nature of each) and (ii) reconciliation between payments or recoveries on (or
with respect to) each Receivable and the amounts from time to time deposited in
the Collection Account in respect of such Receivable.

     (e) COAF shall maintain (or shall cause its Sub-Servicer to maintain) its
computer systems so that, from time to time after the conveyance under this
Agreement of the Receivables, the master computer records (including any backup
archives) that refer to a Receivable shall indicate clearly the interest of the
Purchaser (or any subsequent assignee of the Purchaser) in such Receivable and
that such Receivable is owned by such Person. Indication of such Peron's

                                                              Purchase Agreement

                                       -5-

<PAGE>

interest in a Receivable shall not be deleted from or modified on such computer
systems until, and only until, the related Receivable shall have been paid in
full or repurchased.

     (f) If at any time COAF shall propose to sell, grant a security interest in
or otherwise transfer any interest in motor vehicle receivables to any
prospective purchaser, lender or other transferee, COAF shall give to such
prospective purchaser, lender or other transferee computer tapes, records or
printouts (including any restored from backup archives) that, if they shall
refer in any manner whatsoever to any Receivable, shall indicate clearly that
such Receivable has been sold and is owned by the Purchaser (or any subsequent
assignee of the Purchaser).

     SECTION 3.5 Other Liens or Interests. Except for the conveyances and grants
of security interests pursuant to this Agreement and the other Transaction
Documents, COAF shall not sell, pledge, assign or transfer the Receivables or
other property transferred to the Purchaser to any other Person, or grant,
create, incur, assume or suffer to exist any Lien (other than Permitted Liens)
on any interest therein, and COAF shall defend the right, title and interest of
the Purchaser in, to and under such Receivables or other property transferred to
the Purchaser against all claims of third parties claiming through or under
COAF.

                                   ARTICLE IV

                                  MISCELLANEOUS

     SECTION 4.1 Transfers Intended as Sale; Security Interest.

     (a) Each of the parties hereto expressly intends and agrees that the
transfers contemplated and effected under this Agreement are complete and
absolute sales and transfers rather than pledges or assignments of only a
security interest and shall be given effect as such for all purposes. It is
further the intention of the parties hereto that the Receivables and related
Purchased Assets shall not be part of COAF's estate in the event of a bankruptcy
or insolvency of COAF. The sales and transfers by COAF of the Receivables and
related Purchased Assets hereunder are and shall be without recourse to, or
representation or warranty (express or implied) by, COAF, except as otherwise
specifically provided herein. The limited rights of recourse specified herein
against COAF are intended to provide a remedy for breach of representations and
warranties relating to the condition of the property sold, rather than to the
collectibility of the Receivables.

     (b) Notwithstanding the foregoing, in the event that the Receivables and
other Purchased Assets are held to be property of COAF, or if for any reason
this Agreement is held or deemed to create indebtedness or a security interest
in the Receivables and other Purchased Assets, then it is intended that:

          (i) This Agreement shall be deemed to be a security agreement within
     the meaning of Articles 8 and 9 of the New York Uniform Commercial Code and
     the Uniform Commercial Code of any other applicable jurisdiction;

          (ii) The conveyances provided for in Section 2.1 and Section 2.2 shall
     be deemed to be a grant by COAF of, and COAF hereby grants to the
     Purchaser, a security interest in all of its right (including the power to
     convey title thereto), title and interest,

                                                              Purchase Agreement

                                       -6-

<PAGE>

     whether now owned or hereafter acquired, in and to the Receivables and
     other Purchased Assets, to secure such indebtedness and the performance of
     the obligations of COAF hereunder;

          (iii) The possession by the Purchaser or its agent of the Receivables
     files and any other property as constitute instruments, money, negotiable
     documents or chattel paper shall be deemed to be "possession by the secured
     party" or possession by the purchaser or a person designated by such
     purchaser, for purposes of perfecting the security interest pursuant to the
     New York Uniform Commercial Code and the Uniform Commercial Code of any
     other applicable jurisdiction; and

          (iv) Notifications to persons holding such property, and
     acknowledgments, receipts or confirmations from persons holding such
     property, shall be deemed to be notifications to, or acknowledgments,
     receipts or confirmations from, bailees or agents (as applicable) of the
     Purchaser for the purpose of perfecting such security interest under
     applicable law.

     SECTION 4.2 Notices, Etc. All demands, notices and communications hereunder
shall be in writing and shall be delivered or mailed by registered or certified
first-class United States mail, postage prepaid, hand delivery, prepaid courier
service, or by Electronic Transmission, and addressed in each case as specified
on Schedule II to the Sale and Servicing Agreement or at such other address as
shall be designated by any of the foregoing in a written notice to the other
parties hereto. Any notice required or permitted to be mailed to a Noteholder
shall be given by first class mail, postage prepaid, at the address of such
Noteholder as shown in the Note Register. Delivery shall occur only upon receipt
or reported tender of such communication by an officer of the recipient entitled
to receive such notices located at the address of such recipient for notices
hereunder; provided, however, that any notice to a Noteholder mailed within the
time prescribed in this Agreement shall be conclusively presumed to have been
duly given, whether or not the Noteholder shall receive such notice.

     SECTION 4.3 Choice of Law. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE INTERNAL, SUBSTANTIVE LAWS OF THE STATE OF NEW
YORK WITHOUT REFERENCE TO THE RULES THEREOF RELATING TO CONFLICTS OF LAW AND THE
OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS.

     SECTION 4.4 Headings. The section headings hereof have been inserted for
convenience only and shall not be construed to affect the meaning, construction
or effect of this Agreement.

     SECTION 4.5 Counterparts. This Agreement may be executed in any number of
counterparts, each of which so executed shall be deemed to be an original, but
all of such counterparts shall together constitute but one and the same
instrument.

     SECTION 4.6 Amendment.

<PAGE>

     (a) Any term or provision of this Agreement may be amended by COAF and the
Purchaser without the consent of the Indenture Trustee, any Noteholder, the
Issuer or the Owner Trustee; provided that such amendment shall not, as
evidenced by an Opinion of Counsel delivered to the Indenture Trustee materially
and adversely affect the interests of the Noteholders; provided, further, that
such amendment shall not materially and adversely affect the rights or
obligations of the Swap Counterparty or the Issuer under the Interest Rate Swap
Agreement unless the Swap Counterparty shall have consented in writing to such
amendment (and such consent shall be deemed to have been given if the Swap
Counterparty does not object in writing within ten (10) Business Days after
receipt of a written request for such consent); provided, further, that any
amendment requiring the Swap Counterparty's consent hereunder must also satisfy
the Rating Agency Condition to be effective.

     (b) Any term or provision of this Agreement may be amended by COAF and the
Purchaser but without the consent of the Indenture Trustee, any Noteholder, the
Issuer, the Owner Trustee or any other Person to add, modify or eliminate any
provisions as may be necessary or advisable in order to enable the Seller, the
Servicer or any of their Affiliates to comply with or obtain more favorable
treatment under any law or regulation or any accounting rule or principle, it
being a condition to any such amendment that the Rating Agency Condition shall
have been satisfied.

     (c) This Agreement may also be amended from time to time by COAF and the
Purchaser, with the consent of the Holders of Notes evidencing not less than a
majority of the aggregate principal amount of the Outstanding Notes, voting as a
single class, for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Agreement or of modifying in
any manner the rights of the Noteholders; provided, that such amendment shall
not materially and adversely affect the rights or obligations of the Swap
Counterparty or the Issuer under the Interest Rate Swap Agreement unless the
Swap Counterparty shall have consented in writing to such amendment (and such
consent shall be deemed to have been given if the Swap Counterparty does not
object in writing within ten (10) Business Days after receipt of a written
request for such consent); provided, further, that any amendment requiring the
Swap Counterparty's consent hereunder must also satisfy the Rating Agency
Condition to be effective. It will not be necessary for the consent of
Noteholders to approve the particular form of any proposed amendment or consent,
but it will be sufficient if such consent approves the substance thereof. The
manner of obtaining such consents (and any other consents of Noteholders
provided for in this Agreement) and of evidencing the authorization of the
execution thereof by Noteholders will be subject to such reasonable requirements
as the Indenture Trustee may prescribe, including the establishment of record
dates pursuant to the Note Depository Agreement.

     (d) Prior to the execution of any such amendment, COAF shall provide
written notification of the substance of such amendment to each Rating Agency;
and promptly after the execution of any such amendment or consent, COAF shall
furnish a copy of such amendment or consent to each Rating Agency and the
Indenture Trustee.

     (e) Prior to the execution of any amendment to this Agreement, the
Purchaser, the Owner Trustee and the Indenture Trustee shall be entitled to
receive and conclusively rely upon an Opinion of Counsel stating that the
execution of such amendment is authorized or permitted

by this Agreement and that all conditions precedent to the execution and
delivery of such amendment have been satisfied. The Owner Trustee and the
Indenture Trustee may, but shall not be obligated to, enter into any such
amendment which adversely affects the Owner Trustee's or the Indenture
Trustee's, as applicable, own rights, duties or immunities under this Agreement.

     SECTION 4.7 Waivers. No failure or delay on the part of the Purchaser, the
Servicer, COAF, the Issuer or the Indenture Trustee in exercising any power or
right hereunder (to the extent such Person has any power or right hereunder)
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such power or right preclude any other or further exercise thereof or the
exercise of any other power or right. No notice to or demand on the Purchaser or
COAF in any case shall entitle it to any notice or demand in similar or other
circumstances. No waiver or approval by the Purchaser under this Agreement
shall, except as may otherwise be stated in such waiver or approval, be
applicable to subsequent transactions. No waiver or approval under this
Agreement shall require any similar or dissimilar waiver or approval thereafter
to be granted hereunder.

complete integration of all prior expressions by the parties hereto with respect
to the subject matter thereof and shall constitute the entire agreement among

prior oral or written understandings. There are no unwritten agreements among
the parties.

     SECTION 4.9 Severability of Provisions. If any one or more of the
covenants, agreements, provisions or terms of this Agreement shall be for any
reason whatsoever held invalid, then such covenants, agreements, provisions or
terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement.

     SECTION 4.10 Binding Effect; Assignability. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns. This Agreement shall create and constitute the
continuing obligations of the parties hereto in accordance with its terms, and
shall remain in full force and effect until such time as the parties hereto
shall agree.

pledge, assignment and grant of a security interest in the Receivables and the
other Purchased Assets by the Issuer to the Indenture Trustee pursuant to the
Indenture for the benefit of the Noteholders. In addition, COAF hereby

Indenture Trustee will have the right to exercise all powers, privileges and
claims of the Purchaser under this Agreement.
