1.   Basis of Presentation

The  accompanying  unaudited  condensed  consolidated  financial  statements  of
O'Reilly Automotive, Inc. and Subsidiaries (the "Company") have been prepared in
accordance  with United States  generally  accepted  accounting  principles  for
interim  financial  information and the instructions to Form 10-Q and Article 10
of Regulation S-X.  Accordingly,  they do not include all of the information and
footnotes required by U.S. generally accepted accounting principles for complete
financial statements. In the opinion of management,  all adjustments (consisting
of normal recurring accruals)  considered necessary for a fair presentation have
been included.  Operating results for the three months ended March 31, 2005, are
not  necessarily  indicative  of the results  that may be expected  for the year
ended  December 31, 2005.  For further  information,  refer to the  consolidated
financial  statements  and footnotes  thereto  included in the Company's  Annual
Report on Form 10-K for the year ended December 31, 2004 ("2004 Form 10-K").

2.   Stock-based Compensation

The Company has elected to use the  intrinsic  value  method of  accounting  for
stock  options  issued  under our stock option  plans and  accordingly  does not
record an expense for such stock options.  For purposes of pro forma disclosures
under  the fair  value  method,  the  estimated  fair  value of the  options  is
amortized to expense over the options'  vesting period.  The Company's pro forma
information for the quarters ended March 31, is as follows:

3.   Synthetic Lease Facility

On June 26, 2003, we completed an amended and restated master agreement relating
to our properties leased from SunTrust Equity Funding, LLC ("the Facility"). The
terms of the amended and restated  Facility  provide for an initial lease period
of five years,  a residual  value  guarantee of  approximately  $43.2 million at
March 31,  2005,  and purchase  options on the  properties.  The  Facility  also
contains a provision  for an event of default  whereby  the lessor,  among other
things, may require us to purchase any or all of the properties.  One additional
renewal  period of five years may be  requested  from the lessor,  although  the
lessor is not  obligated to grant such  renewal.  The  agreement  with  SunTrust
Equity  Funding,  LLC has been recorded and  disclosed as an operating  lease in
accordance with Financial  Accounting  Standards Board Statement No. 13 and FASB
Interpretation No. 46 and 46R.

5.   Recent Accounting Pronouncements

In November 2004, the FASB issued SFAS 151, Inventory Costs, an amendment of ARB
No. 43,  Chapter 4. The standard requires that abnormal amounts of idle capacity
and spoilage  costs should be excluded  from the cost of inventory  and expensed
when  incurred.  The standard is effective for fiscal  periods  beginning  after
June 15,  2005.  We do not  expect the  adoption  of this  standard  will have a
material effect on our financial position, results of operations or cash flows.

In December 2004, the FASB issued SFAS 153,  Exchanges of Nonmonetary Assets, an
amendment  of APB No. 29,  Accounting  for  Nonmonetary  Transactions.  SFAS 153
requires  exchanges  of  productive  assets to be  accounted  for at fair value,
rather than at carryover  basis,  unless  (1) neither the asset received nor the
asset surrendered has a fair value that is determinable within reasonable limits
or (2) the  transactions  lack commercial  substance.  SFAS 153 is effective for
nonmonetary asset exchanges occurring in fiscal periods beginning after June 15,
2005. We do not expect the adoption of this standard will have a material effect
on our financial position, results of operations or cash flows.

In  December 2004,  the FASB issued SFAS  No. 123R,  Share-Based  Payment.  SFAS
No. 123R is a revision of SFAS No. 123, Accounting for Stock Based Compensation,
and supersedes APB 25. Among other items, SFAS 123R eliminates the use of APB 25
and the  intrinsic  value  method  of  accounting,  and  requires  companies  to
recognize  the cost of employee  services  received  in  exchange  for awards of
equity  instruments,  based on the grant date fair value of those awards, in the
financial  statements.  The effective  date of SFAS 123R is the first  reporting
period beginning after January 1, 2006, which is first quarter 2006 for calendar
year companies, such as ourselves, although early adoption is allowed. SFAS 123R
permits   companies  to  adopt  its   requirements   using  either  a  "modified
prospective" method, or a "modified  retrospective"  method. Under the "modified
prospective" method, compensation cost is recognized in the financial statements
beginning with the effective  date,  based on the  requirements of SFAS 123R for
all share-based  payments granted after that date, and based on the requirements
of SFAS 123 for all unvested  awards granted prior to the effective date of SFAS
123R. Under the "modified  retrospective"  method, the requirements are the same
as under the "modified prospective" method, but also permits entities to restate
financial  statements of previous periods based on pro forma disclosures made in
accordance  with SFAS 123. We currently  utilize a standard option pricing model
(i.e.,  Black-Scholes)  to measure  the fair value of stock  options  granted to
employees. While SFAS 123R permits entities to continue to use such a model, the
standard also permits the use of a "lattice"  model.  We have not yet determined
which model we will use to measure the fair value of employee stock options upon
the  adoption  of SFAS  123R.  See Note 8 of the  Company's  2004  Form 10-K for
further  information.  SFAS 123R also requires that the benefits associated with
the tax  deductions in excess of recognized  compensation  cost be reported as a
financing  cash flow,  rather than as an operating  cash flow as required  under
current  literature.  This  requirement will reduce net operating cash flows and
increase net financing  cash flows in periods after the  effective  date.  These
future amounts cannot be estimated,  because they depend on, among other things,
when employees  exercise stock  options.  However,  the amount of operating cash
flows  recognized in prior periods for such excess tax  deductions,  as shown in
our  Consolidated   Statement  of  Cash  Flows  of  the  2004  Form  10-K,  were
$4.5 million,  $5.5 million,  and $1.5 million, for the years ended December 31,
2004,  2003,  and 2002,  respectively.  We  currently  expect to adopt SFAS 123R
effective  January 1, 2006;  however,  we have not yet  determined  which of the
aforementioned  adoption  methods  we  will  use and are  still  evaluating  the
standard.  See Note 8 of the Company's 2004 Form 10-K for further information on
our stock-based compensation plans.

references to the "Company" or "O'Reilly" refer to O'Reilly Automotive, Inc. and
its subsidiaries.

Critical Accounting Policies and Estimates

The  fundamental   objective  of  financial   reporting  is  to  provide  useful
information  that allows a reader to comprehend  the business  activities of our
company. To aid in that  understanding,  management has identified our "critical
accounting  policies."  These  policies  have  the  potential  to  have  a  more
significant  impact  on  our  financial   statements,   either  because  of  the
significance  of the financial  statement item to which they relate,  or because
they  require  judgment  and  estimation  due to  the  uncertainty  involved  in
measuring, at a specific point in time, events which are continuous in nature.

o    Cost of goods sold - Cost of goods sold includes warehouse and distribution
     expenses and estimates of amounts due from vendors for certain  merchandise
     allowances  and rebates.  These  estimates are consistent  with  historical
     experience.

o    Operating, selling, general and administrative expense (OSG&A) - Operating,
     selling, general and administrative expense includes estimates for medical,
     worker's  compensation and other general liability  insurance  obligations,
     which  are  partially  based  on  estimates  of  certain  claim  costs  and
     historical experience.

o    Accounts receivable - Allowance for doubtful accounts is estimated based on
     historical  loss  ratios  and  consistently  has been  within  management's
     expectations.

o    Revenue -  Over-the-counter  retail  sales are  recorded  when the customer
     takes  possession of merchandise.  Sales to professional  installers,  also
     referred  to  as  "commercial   sales",   are  recorded  upon  delivery  of
     merchandise to the customer, generally at the customer's place of business.
     Wholesale sales to other retailers,  also referred to as "jobber sales" are
     recorded  upon  shipment  of  merchandise.  All sales are  recorded  net of
     estimated allowances and discounts.

o    Vendor  concessions  - The Company  receives  concessions  from its vendors
     through a variety of  programs  and  arrangements,  including  co-operative
     advertising,   allowances  for  warranties  and  volume  purchase  rebates.
     Co-operative advertising allowances that are incremental to our advertising
     program,  specific to a product or event and  identifiable  for  accounting
     purposes are reported as a reduction of  advertising  expense in the period
     in which  the  advertising  occurred.  All  other  vendor  concessions  are
     recognized  as a  reduction  of  cost  of  sales  when  recognized  in  the
     consolidated statement of income.

o    Stock-based  compensation  - We have  elected  to use the  intrinsic  value
     method of accounting  for stock options issued under our stock option plans
     and  accordingly  do not record an  expense  for such  stock  options.  For
     purposes  of pro  forma  disclosures  under  the  fair  value  method,  the
     estimated  fair value of the  options  is  amortized  to  expense  over the
     options'  vesting  period.  Our pro forma  information  for the years ended
     March 31, is as follows:

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
RESULTS OF OPERATIONS AND FINANCIAL CONDITION (CONT.)

Results of Operations

Product sales increased $62.9 million, or 15.6% from $403.3 million in the first
quarter of 2004, to $466.2  million in the first quarter of 2005.  This increase
was  primarily due to the opening of 37 net, new stores during the first quarter
of 2005, in addition to a 7.1%  increase in  comparable  store product sales for
the first quarter of 2005.  Comparable  store product sales are calculated based
on the  change in  product  sales of stores  open at least one year.  Percentage
increase in comparable  store  product sales is calculated  based on store sales
results,  which exclude sales of specialty machinery,  sales by outside salesmen
and sales to employees.  At March 31, 2005, we operated 1,286 stores compared to
1,132 stores at March 31, 2004.

Gross profit increased $26.6 million,  or 15.7% from $169.6 million (or 42.1% of
product  sales) in the first  quarter of 2004,  to $196.2  million  (or 42.1% of
product  sales) in the first  quarter  of 2005.  The  increase  in gross  profit
dollars was  primarily  a result of the  increase  in sales  resulting  from the
increase in the number of stores open during the first  quarter of 2005 compared
to the same period in 2004, and increased sales levels at existing stores.

Operating,  selling,  general and  administrative  expenses  ("OSG&A  expenses")
increased  $17.0  million,  or 13.6% from  $125.6  million  (or 31.2% of product
sales)  in the first  quarter  of 2004 to $142.6  million  (or 30.6% of  product
sales) in the first  quarter of 2005.  The  dollar  increase  in OSG&A  expenses
resulted from the addition of team members and resources in order to support the
increased  level  of  our  operations.  The  decrease  in  OSG&A  expenses  as a
percentage of product sales was primarily due to economies of scale achieved and
the result of management's efforts to increase labor productivity.

Our estimated provision for income taxes increased $3.4 million to $19.7 million
for the first  quarter of 2005  compared to the same period in 2004, as a result
of our  increased  taxable  income.  Our  effective tax rate was 37.2% of income
before  income  taxes  for the  first  quarter  of 2005 and  37.4% for the first
quarter of 2004.

Principally,  as a result of the foregoing,  income before  cumulative effect of
accounting change increased from $27.3 million (or 6.8% of product sales) in the
first quarter of 2004 to $33.2  million (or 7.1% of product  sales) in the first
quarter of 2005.

Liquidity and Capital Resources

Net cash provided by operating  activities  decreased from $80.5 million for the
first three months in 2004 to $64.4  million for the first three months of 2005.
This decrease was principally  the result of an increase in inventory  primarily
due to our continuing  store growth and the opening of the Atlanta  distribution
center and a smaller increase in accounts payable.

Net cash used in investing  activities  increased  from $38.4 million during the
first three months in 2004 to $49.4 million for the  comparable  period in 2005,
primarily  due to increases in notes  receivable  and  purchases of property and
equipment.

Net cash provided by financing  activities increased from ($17.9) million in the
first three  months of 2004 to $5.3  million in the first three  months of 2005,
primarily due to a decrease in principal payments on long-term debt.

We have available an unsecured,  three-year syndicated revolving credit facility
in the amount of $150 million.  The credit  facility is guaranteed by all of our
subsidiaries  and may be  increased  to a  total  of $200  million,  subject  to
availability  of such  additional  credit from either  existing banks within the
syndicate  or other  banks.  At March 31,  2005,  none of the  revolving  credit
facility was outstanding. Additionally, letters of credit totaling $21.2 million
were outstanding at March 31, 2005. Accordingly,  we have aggregate availability
for additional borrowings of $128.8 million under the revolving credit facility.
The  revolving  credit  facility,  which  bears  interest at LIBOR plus a spread
ranging from 0.875% to 1.375% (0.875% at March 31, 2005), expires in July 2005.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
RESULTS OF OPERATIONS AND FINANCIAL CONDITION (CONT.)

Our continuing store expansion program requires significant capital expenditures
and working capital principally for inventory requirements. The costs associated
with  the  opening  of a new  store  (including  the  cost of land  acquisition,
improvements,  fixtures,  inventory  and computer  equipment)  are  estimated to
average  approximately  $900,000  to $1.1  million;  however,  such costs may be
significantly  reduced  where we lease,  rather than  purchase,  the store site.
Although the cost to acquire the business of an independently  owned parts store
varies, depending primarily upon the amount of inventory and the amount, if any,
of real estate being acquired, we estimate that the average cost to acquire such
a  business  and  convert  it to one of our  stores is  approximately  $400,000,
exclusive of the cost of  inventory.  We plan to finance our  expansion  program
through cash expected to be provided  from  operating  activities  and available
borrowings under our existing credit facilities.

During the first three months of 2005, we opened 37 net, new stores. The Company
plans to open 123  additional  stores  during the  remainder of 2005.  The funds
required  for such planned  expansions  are expected to be provided by operating
activities and the existing and available bank credit facilities.

We believe that our existing cash, short-term  investments,  cash expected to be
provided by operating  activities,  available  bank credit  facilities and trade
credit will be sufficient to fund both our short-term and long-term  capital and
liquidity needs for the foreseeable future.

Off Balance Sheet Arrangements

We have utilized various  financial  instruments from time to time as sources of
cash when such instruments provided a cost effective alternative to our existing
sources  of cash.  We do not  believe,  however,  that we are  dependent  on the
availability of these  instruments to fund our working  capital  requirements or
our growth plans.

On December 29, 2000, we completed a sale-leaseback transaction. Under the terms
of the  transaction,  we sold  90  properties,  including  land,  buildings  and
improvements, which generated $52.3 million of additional cash. The lease, which
is being accounted for as an operating lease, provides for an initial lease term
of 21  years  and  may be  extended  for one  initial  ten-year  period  and two
additional  successive  periods of five years each.  The resulting  gain of $4.5
million has been  deferred and is being  amortized  over the initial lease term.
Net rent  expense  during the initial  term will be  approximately  $5.5 million
annually.

In August 2001, we completed a sale-leaseback with  O'Reilly-Wooten 2000 LLC (an
entity owned by certain  shareholders of the Company).  The transaction involved
the sale and  leaseback  of nine  O'Reilly  Auto Parts  stores and  resulted  in
approximately  $5.6 million of additional  cash to the Company.  The transaction
did not result in a material gain or loss.  The lease,  which has been accounted
for as an  operating  lease,  calls for an  initial  term of 15 years with three
five-year renewal options.

On June 26, 2003, we completed an amended and restated  master  agreement to our
$50 million  Synthetic  Operating  Lease Facility (the Facility or the Synthetic
Lease) with a group of financial institutions. The terms of the Facility provide
for an initial  lease  period of five  years,  a  residual  value  guarantee  of
approximately  $43.2 million at December 31, 2004,  and purchase  options on the
properties.  The  Facility  also  contains a  provision  for an event of default
whereby the lessor, among other things, may require us to purchase any or all of
the  properties.  One  additional  renewal period of five years may be requested
from the lessor, although the lessor is not obligated to grant such renewal. The
Facility has been  accounted for as an operating  lease under the  provisions of
Financial  Accounting  Standards Board (FASB) Statement of Financial  Accounting
Standards   (SFAS)  No.  13  and   related   interpretations,   including   FASB
Interpretation No. 46.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
RESULTS OF OPERATIONS AND FINANCIAL CONDITION (CONT.)

Off Balance Sheet Arrangements (continued)

We issue stand-by letters of credit provided by a $30 million sublimit under the
Credit  Facility that reduce our available  borrowings.  These letters of credit
are  issued  primarily  to satisfy  the  requirements  of workers  compensation,
general  liability  and  other  insurance  policies.  Substantially  all  of the
outstanding letters of credit have a one-year term from the date of issuance and
have been issued to replace surety bonds that were previously issued. Letters of
credit  totaling  $21.2 million and $13.8 million were  outstanding at March 31,
2005 and 2004, respectively.

New Accounting Standards

In November 2004, the FASB issued SFAS 151, Inventory Costs, an amendment of ARB
No. 43,  Chapter 4. The standard requires that abnormal amounts of idle capacity
and spoilage  costs should be excluded  from the cost of inventory  and expensed
when  incurred.  The standard is effective for fiscal  periods  beginning  after
June 15,  2005.  We do not  expect the  adoption  of this  standard  will have a
material effect on our financial position, results of operations or cash flows.

In December 2004, the FASB issued SFAS 153,  Exchanges of Nonmonetary Assets, an
amendment  of APB No. 29,  Accounting  for  Nonmonetary  Transactions.  SFAS 153
requires  exchanges  of  productive  assets to be  accounted  for at fair value,
rather than at carryover  basis,  unless  (1) neither the asset received nor the
asset surrendered has a fair value that is determinable within reasonable limits
or (2) the  transactions  lack commercial  substance.  SFAS 153 is effective for
nonmonetary asset exchanges occurring in fiscal periods beginning after June 15,
2005. We do not expect the adoption of this standard will have a material effect
on our financial position, results of operations or cash flows.

In  December 2004,  the FASB issued SFAS  No. 123R,  Share-Based  Payment.  SFAS
No. 123R is a revision of SFAS No. 123, Accounting for Stock Based Compensation,
and supersedes APB 25. Among other items, SFAS 123R eliminates the use of APB 25
and the  intrinsic  value  method  of  accounting,  and  requires  companies  to
recognize  the cost of employee  services  received  in  exchange  for awards of
equity  instruments,  based on the grant date fair value of those awards, in the
financial  statements.  The effective  date of SFAS 123R is the first  reporting
period beginning after January 1, 2006, which is first quarter 2006 for calendar
year companies, such as ourselves, although early adoption is allowed. SFAS 123R
permits   companies  to  adopt  its   requirements   using  either  a  "modified
prospective" method, or a "modified  retrospective"  method. Under the "modified
prospective" method, compensation cost is recognized in the financial statements
beginning with the effective  date,  based on the  requirements of SFAS 123R for
all share-based  payments granted after that date, and based on the requirements
of SFAS 123 for all unvested  awards granted prior to the effective date of SFAS
123R. Under the "modified  retrospective"  method, the requirements are the same
as under the "modified prospective" method, but also permits entities to restate
financial  statements of previous periods based on pro forma disclosures made in
accordance  with SFAS 123. We currently  utilize a standard option pricing model
(i.e.,  Black-Scholes)  to measure  the fair value of stock  options  granted to
employees. While SFAS 123R permits entities to continue to use such a model, the
standard also permits the use of a "lattice"  model.  We have not yet determined
which model we will use to measure the fair value of employee stock options upon
the adoption of SFAS 123R.  See Note 8 of the  Company's  Annual  Report on Form
10-K for the year ended  December  31,  2004  ("2004  Form  10-K")  for  further
information.  SFAS 123R also requires that the benefits  associated with the tax
deductions in excess of recognized  compensation cost be reported as a financing
cash flow,  rather  than as an  operating  cash flow as required  under  current
literature.  This  requirement will reduce net operating cash flows and increase
net  financing  cash flows in periods  after the  effective  date.  These future
amounts  cannot be estimated,  because they depend on, among other things,  when
employees  exercise stock options.  However,  the amount of operating cash flows
recognized  in prior  periods  for such excess tax  deductions,  as shown in our
Consolidated  Statement of Cash Flows of the 2004 Form 10-K, were  $4.5 million,
$5.5 million, and $1.5 million, for the years ended December 31, 2004, 2003, and
2002, respectively.  We currently expect to adopt SFAS 123R effective January 1,
2006; however,  we have not yet determined which of the aforementioned  adoption
methods we will use and are still  evaluating  the  standard.  See Note 8 of the
Company's 2004 Form 10-K for further information on our stock-based compensation
plans.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
RESULTS OF OPERATIONS AND FINANCIAL CONDITION (CONT.)

Inflation and Seasonality

We attempt to mitigate the effects of merchandise cost increases  principally by
taking advantage of vendor incentive programs, economies of scale resulting from
increased volume of purchases and selective  forward buying.  As a result, we do
not believe that our operations have been materially affected by inflation.  Our
business is somewhat  seasonal,  primarily  as a result of the impact of weather
conditions on store sales. Store sales and profits have historically been higher
in the second and third quarters (April through  September) of each year than in
the first and fourth quarters.

Internet Address and Access to SEC Filings

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
RESULTS OF OPERATIONS AND FINANCIAL CONDITION (CONT.)

Forward-Looking Statements

We claim the protection of the safe-harbor for forward-looking statements within
the meaning of the Private  Securities  Litigation  Reform Act of 1995.  You can
identify these statements by forward-looking  words such as "expect," "believe,"
"anticipate," "good," "plan," "intend," "estimate," "project," "will" or similar
words.  In  addition,  statements  contained  within  this  filing  that are not
historical facts are forward-looking  statements,  such as statements discussing
among other things,  expected growth,  store development and expansion strategy,
business   strategies,   future   revenues   and   future   performance.   These
forward-looking  statements  are based on  estimates,  projections,  beliefs and
assumptions and are not guarantees of future events and results. Such statements
are subject to risks, uncertainties and assumptions,  including, but not limited
to,  competition,  product  demand,  the market for auto  parts,  the economy in
general, inflation, consumer debt levels, governmental approvals, our ability to
hire and retain  qualified  employees,  risks associated with the integration of
acquired businesses,  weather,  terrorist activities, war and the threat of war.
Actual  results may  materially  differ from  anticipated  results  described or
implied in these  forward-looking  statements.  Please  refer to Exhibit 99.1 of
this Form  10-Q,  for  additional  factors  that  could  materially  affect  our
financial performance.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are  subject  to  interest  rate risk to the  extent we  borrow  against  our
revolving  credit facility with variable  interest rates.  Since no amounts were
outstanding  under the revolving  credit facility at March 31, 2005,  changes in
interest  rates would not have any effect.  In the event of an adverse change in
interest rates and assuming the Company had amounts outstanding under the credit
facility,  management would likely take actions that would mitigate our exposure
to interest  rate risk  particularly  if our  borrowing  levels  increase to any
significant extent; however, due to the uncertainty of the actions that would be
taken and their possible effects, this analysis assumes no such action. Further,
this  analysis  does not  consider  the  effects  of the  change in the level of
overall economic activity that could exist in such an environment.

ITEM 4.  CONTROLS AND PROCEDURES

The Company's  management,  under the supervision and with the  participation of
our chief  executive  officer and chief  financial  officer,  has  reviewed  and
evaluated the effectiveness of the Company's  disclosure controls and procedures
as of March 31, 2005.  Based on such review and evaluation,  our chief executive
officer and chief financial officer have concluded that the disclosure  controls
and  procedures  were  effective  as of  March  31,  2005,  to  ensure  that the
information required to be disclosed by the Company in the reports that it files
or  submits  under the  Securities  Exchange  Act of 1934,  as  amended,  (a) is
recorded, processed, summarized and reported within the time period specified in
the  SEC's  rules  and  forms and (b) is  accumulated  and  communicated  to the
Company's  management,  including the officers,  as  appropriate to allow timely
decisions regarding required  disclosure.  There were no material changes in the
Company's internal control over financial  reporting during the first quarter of
2005 that have materially affected or are reasonably likely to materially affect
the Company's internal controls over financial reporting.

                       Exhibit 99.1 - Certain Risk Factors


Some of the  information  in this Form 10-Q contains and future  reports,  press
releases and other public  information  may contain  forward-looking  statements
that  involve  substantial  risks  and  uncertainties.  You can  identify  these
statements  by   forward-looking   words  such  as  "may,"   "will,"   "expect,"
"anticipate,"  "believe,"  "estimate,"  and "continue" or similar  words.  These
"forward-looking   statements"  are  made  in  reliance  upon  the  safe  harbor
provisions of the Private Securities  Litigation Reform Act of 1995 (See Section
27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934.) You should read statements that contain these words carefully  because
they: (1) discuss our future expectations; (2) contain projections of our future
results  of  operations  or of  our  financial  condition;  or (3)  state  other
"forward-looking"  information.  We believe it is important to  communicate  our
expectations to our investors.  However,  there may be events in the future that
we are not able to accurately predict or over which we have no control.

The risk factors listed in this exhibit,  as well as any cautionary  language in
this Form 10-Q, are subject to risks, uncertainties and assumptions,  including,
but not limited to, competition,  product demand, the market for auto parts, the
economy in general, inflation, consumer debt levels, governmental approvals, our
ability  to hire and  retain  qualified  employees,  risks  associated  with the
integration of acquired business,  weather,  terrorist  activities,  war and the
threat of war.  Actual results may materially  differ from  anticipated  results
described  in these  forward-looking  statements.  You  should be aware that the
occurrence  of the events  described in these risk factors and  elsewhere in our
annual report on Form 10-K for the year ended  December 31, 2004 (the "2004 Form
10-K") could have a material adverse effect on our business,  operating  results
and financial condition.

Competition

We  compete  with a large  number of retail  (DIY) and  wholesale  (professional
installers)  automotive  aftermarket  product  suppliers.  The  distribution  of
automotive  aftermarket products is a highly competitive industry,  particularly
in the more densely  populated market areas that we serve.  Competitors  include
national and regional automotive parts chains,  independently owned parts stores
(some  of  which  are  associated  with  national  auto  parts  distributors  or
associations), automobile dealerships, mass or general merchandise, discount and
convenience  chains  that  carry  automotive  products,   independent  warehouse
distributors   and  parts  stores  and  national   warehouse   distributors  and
associations.  Some of our  competitors  are larger than we are and have greater
financial  resources.  In addition,  some of our competitors are smaller than we
are overall but have a greater presence than we do in a particular market. For a
list of our principal  competitors,  see the "Competition"  section of Item 1 to
our 2004 Form 10-K.

No Assurance of Future Growth

We believe that our ability to open  additional  stores at an  accelerated  rate
will be a significant  factor in achieving our growth objectives for the future.
Failure to achieve our growth objectives may negatively impact the trading price
of our  common  stock.  Our  ability to  accomplish  our  growth  objectives  is
dependent,  in part, on matters beyond our control,  such as weather conditions,
zoning and other issues related to new store site development,  the availability
of qualified  management personnel and general business and economic conditions.
We cannot be sure that our growth  plans for 2005 and beyond  will be  achieved.
For a  discussion  of our  growth  strategies,  see the  "Growth  and  Expansion
Strategies" section of Item 1 to our 2004 Form 10-K.

Acquisitions May Not Lead to Expected Growth

We expect to continue to make acquisitions as an element of our growth strategy.
Acquisitions  involve certain risks that could cause our actual growth to differ
from  our  expectations.  For  example:  (1) we may not be able to  continue  to
identify suitable  acquisition  candidates or to acquire additional companies at
favorable prices or on other favorable terms; (2) our management's attention may
be  distracted;  (3) we may fail to retain key  acquired  personnel;  (4) we may
assume unanticipated legal liabilities and other problems; and (5) we may not be
able to successfully integrate the operations (accounting and billing functions,
for example) of businesses we acquire to realize economic, operational and other
benefits.

                 Exhibit 99.1 - Certain Risk Factors (continued)

Sensitivity to Regional Economic and Weather Conditions

All of our stores are located in the  Central and  Southern  United  States.  In
particular, approximately 30% of our stores are located in Texas. Therefore, our
business is sensitive to the  economic  and weather  conditions  of this region.
Unusually severe or inclement weather tends to reduce sales, particularly to DIY
customers.

Dependence Upon Key and Other Personnel

Our success has been largely  dependent on the efforts of certain key personnel,
including  David E. O'Reilly,  Ted F. Wise, Greg L. Henslee and James R. Batten.
Our business and results of operations could be materially adversely affected by
the loss of the services of one or more of these individuals.  Additionally, our
successful  implementation and management of our growth and expansion strategies
will  depend  on our  ability  to  continue  to  attract  and  retain  qualified
personnel.  We cannot be sure that we will be able to continue  to attract  such
personnel.  For a further  discussion of our management  and personnel,  see the
"Business"  section  of Item 1 and Item 4a of our 2004  Form  10-K and our Proxy
Statement on Schedule 14A for the 2005 Annual Meeting of Shareholders.

Concentration of Ownership by Management

Our executive  officers and directors as a group  beneficially own a substantial
percentage of the  outstanding  shares of our common stock.  These  officers and
directors have the ability to exercise  effective voting control of the company,
including the election of all of our directors, and to effectively determine the
vote on any matter  being voted on by our  shareholders,  including  any merger,
sale of assets or other change in control of the company.

Possible Volatility of Our Stock Price

The stock  market and the price of our common  stock may be subject to  volatile
fluctuations based on general economic and market  conditions.  The market price
for our common  stock may also be  affected  by our  ability  to meet  analysts'
expectations.  Failure to meet such expectations,  even slightly,  could have an
adverse  effect on the market  price of our common  stock.  In  addition,  stock
market  volatility  has  had a  significant  effect  on  the  market  prices  of
securities  issued by many  companies  for reasons  unrelated  to the  operating
performance of these companies.  In the past, following periods of volatility in
the market price of a company's  securities,  securities class action litigation
has often been  instituted  against such a company.  If similar  litigation were
instituted  against us, it could result in substantial  costs and a diversion of
our management's attention and resources,  which could have an adverse effect on
our business.

Shares Eligible for Future Sale

All of the shares of common stock  currently  held by our affiliates may be sold
in reliance upon the exemptive  provisions of Rule 144 of the  Securities Act of
1933, as amended, subject to certain volume and other conditions imposed by such
rule.  We cannot  predict the  effect,  if any,  that future  sales of shares of
common stock or the availability of such shares for sale will have on the market
price of the common stock  prevailing  from time to time.  Sales of  substantial
amounts of common stock,  or the perception  that such sales might occur,  could
adversely affect the prevailing market price of the common stock.
