                         Report of Independent Auditors

The Plan Administrators and Participants
O'Reilly Automotive, Inc.
Profit Sharing and Savings Plan

We have audited the  accompanying  statements  of net assets  available for plan
benefits (modified cash basis) of the O'Reilly  Automotive,  Inc. Profit Sharing
and Savings  Plan (the Plan) as of December  31, 2002 and 2001,  and the related
statement of changes in net assets  available for plan benefits  (modified  cash
basis) for the year ended December 31, 2002. These financial  statements are the
responsibility  of the Plan's  management.  Our  responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable  assurance about whether the financial  statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting  the amounts and  disclosures in the financial  statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

As described in Note 1, the financial statements and supplemental  schedule were
prepared on the  modified  cash basis of  accounting,  which is a  comprehensive
basis of accounting other than accounting  principles  generally accepted in the
United States.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects, the net assets available for plan benefits (modified cash
basis) as of December 31, 2002 and 2001, and the changes in net assets available
for plan benefits (modified cash basis) for the year ended December 31, 2002, on
the basis of accounting described in Note 1.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying  supplemental  schedule  (modified
cash  basis) of assets  held for  investment  purposes at the end of the year is
presented for purposes of additional  analysis and is not a required part of the
financial statements but is supplementary information required by the Department
of Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement  Income Security Act of 1974. This  supplemental  schedule  (modified
cash basis) is the  responsibility  of the Plan's  management.  The supplemental
schedule  (modified  cash basis) has been  subjected to the auditing  procedures
applied in our audits of the financial statements and, in our opinion, is fairly
stated in all material respects in relation to the financial statements taken as
a whole.

1.   Summary of Significant Accounting Policies

The  following  is a  summary  of the  significant  accounting  policies  of the
O'Reilly  Automotive,  Inc. (the "Company") Profit Sharing and Savings Plan (the
"Plan"):

Basis of Presentation

The  accompanying  financial  statements have been prepared on the modified cash
basis of accounting,  which is a  comprehensive  basis of accounting  other than
generally accepted accounting  principles.  Under this basis,  contributions are
recorded  when  received  rather  than in the period to which they  relate,  and
expenses are recorded when paid rather than when incurred.

Valuation of Investments

The value of investments in common and collective trusts,  registered investment
company  funds and  O'Reilly  Automotive,  Inc.  common stock is based on quoted
market values received from SunTrust Bank, Central Florida,  N.A.  (SunTrust) on
the last business day of the plan year.

Administrative Expenses

The Company pays the administrative expenses of the Plan.

Use of Estimates

The preparation of financial  statements  requires  management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

2.  Description of the Plan

The following  description of the Plan is provided for general information only.
Participants should refer to the plan agreement for a more complete  description
of the Plan's provisions.

The Plan is a defined contribution pension plan providing retirement benefits to
substantially  all  employees  of  the  Company  who  have  attained  age 21 and
completed  six months and at least  1,000  hours of service in a 12  consecutive
month period of employment.  The Plan is sponsored by the Company and is subject
to the pro  visions  of the  Employee  Retirement  Income  Security  Act of 1974
(ERISA).

The  Plan  allows  participants  to  contribute  up  to  100%  of  their  annual
compensation  to the Plan up to $11,000.  The Company has elected to  contribute
50%  of  each  employee's  voluntary  contribution  up to 2% of  the  employee's
compensation and 25% of the next 4% of each employee's  voluntary  contribution.
Additionally, the Company may make voluntary contributions to the Plan annually,
as  determined  by its Board of  Directors,  up to a maximum  aggregate  company
contribution of 15% of participants' annual compensation. Participants may elect
to allocate their  contributions  to their account  balances in various  equity,
bond or fixed income funds or the O'Reilly  Automotive,  Inc.  Stock Fund,  or a
combination  thereof.  However,  all employer  contributions are invested in the
O'Reilly  Automotive,  Inc. Stock Fund. During the year ended December 31, 2002,
the Plan  received  discretionary  contributions  from the Company  amounting to
$2,199,997, not including matching contributions.

Mid States  Automotive  Distributors  Inc. 401(k) Plan was discontinued in 2002.
The net assets of that plan were then transferred into the O'Reilly Plan.

Each participant's  account is credited with the participant's  contribution and
an allocation of the Company's  contribution  and Plan earnings.  Allocations of
Company  contributions are based on participant  contributions and compensation.
Allocations  of Plan  earnings  are  based on  participants'  account  balances.
Forfeitures of terminated  participants' non-vested accounts are allocated based
on participant compensation.  Total forfeitures at the end of 2002, amounting to
$918,341,  were  first  applied  to  administrative  expenses  and then  reduced
employer contributions.

Participants   are   immediately   vested  with   respect  to  their   voluntary
contributions.  During 2002,  the Company  amended the vesting  schedule for the
Plan.  With respect to employer  contributions,  participants  become 20% vested
after two years of service with the Company. Vesting increases in 20% increments
annually to 100% after six years.

Participating  employees  are  entitled  to borrow  from the Plan the  lesser of
$50,000 or 50% of the employee's  vested account  balance at a rate equal to one
percentage  point above the prime interest rate in effect as reported in the The
Wall Street  Journal on the last business day of the month prior to the date the
loan is made.  Loans are  repaid by payroll  deductions  over a period no longer
than five years.

                    Notes to Financial Statements (Continued)

2.   Description of the Plan (continued)



Although  it has not  expressed  any intent to do so, the  Company has the right
under the Plan to discontinue its contributions at any time and to terminate the
Plan  subject  to the  provisions  of ERISA.  In the event of plan  termination,
participants will become 100% vested in their accounts.

Benefit distributions are payable in monthly payments to the beneficiary or in a
lump sum,  as  elected by the  participant.  At  December  31,  2002,  and 2001,
terminated  employees had  approximately  $212,352 and  $408,480,  respectively,
included in net assets available for plan benefits which were to be paid in 2003
and 2002, respectively.  The Plan pays all administrative expenses. During 2002,
administrative   expenses   totaled   $402,800  and  are  included  in  the  net
realized/unrealized   depreciation   in  fair  value  of   investments   in  the
accompanying Statement of Changes in Net Assets Available for Plan Benefits.

3.   Investments

At December 31, 2002, and 2001, the Plan's investments are held by SunTrust,  in
a bank-administered trust fund. SunTrust has authority for the purchase and sale
of investments based on participant discretion,  subject to certain restrictions
as specified in the trust agreement and in ERISA.

The fair value of individual investments that represent 5% or more of the Plan's
net assets are as follows:

5.   Differences Between Financial Statements and Form 5500

The following is a  reconciliation  of net assets available for benefits per the
financial statements to the Form 5500:

                                                 =============    =============


In 2002, the Form 5500 is being prepared based on cash basis  accounting,  which
is consistent with financial  statements.  Accordingly,  there is no accrual for
employer voluntary contribution in 2002.

6.   Income Tax Status

The Plan has received a determination  letter from the Internal  Revenue Service
dated February 7, 1995,  stating that the Plan is qualified under Section 401(a)
of the Internal Revenue Code (the "Code") and,  therefore,  the related trust is
exempt from taxation.  Subsequent to this issuance of the determination  letter,
the Plan was  amended.  Once  qualified,  the Plan is  required  to  operate  in
conformity with the Code to maintain its  qualification.  The Plan Administrator
believes  the  Plan  is  being  operated  in  compliance   with  the  applicable
requirements  of the  Code  and,  therefore,  believes  the Plan as  amended  is
qualified and the related trust is tax exempt.

7.   Related Party Transactions

Certain Plan investments are shares in registered  investment  companies managed
by SunTrust.  SunTrust is the Trustee as  described by the Plan and,  therefore,
these transactions qualify as party-in-interest transactions.
