CSK Auto, Inc. to Acquire Automotive Information Systems

    Acquisition Provides CSK with Comprehensive Diagnostic Vehicle Repair
 Information to be Offered to its Retail, Commercial, and Internet Customers

    PHOENIX, Aug. 18 -- CSK Auto Corporation
announced today that its wholly-owned subsidiary, CSK Auto Inc., the largest
retailer of automotive parts and accessories in the Western United States and
one of the largest such retailers in the country, has signed a definitive
agreement to purchase Automotive Information Systems (AIS).  AIS is a premier
provider of diagnostic vehicle repair information to automotive technicians,
automotive replacement parts manufacturers, automotive test equipment
manufacturers, the Do-It-Yourself consumer and to 
websites.
    This acquisition represents another strategic step in the implementation
of CSK's Internet initiative that was commenced in June 1999 with the launch
of http://WWW.CSKAUTO.COM , the first e-commerce site of a major automotive
aftermarket parts retailer.
    Founded in 1987, AIS has evolved into the nation's best source for
knowledge of what breaks on vehicles, what vehicles it breaks on, and how to
fix those vehicles correctly.  AIS has built this knowledge base through
continual analysis of data.  Data is gathered from (1) the more than
250,000 calls it receives each year from technicians seeking diagnostic
assistance for vehicle repair problems, (2) its staff of 32 Master Technicians
with over 550 years combined years of experience performing vehicle
diagnostics and (3) the nation's most comprehensive on-site library of factory
vehicle service information.
    
        AIS markets its products and services under the brand name IDENTIFIX(TM).
These products and services include: technical hotlines serving more than
15,000 automotive shops; the Repair Trac(TM) Service Bulletin; on-line
diagrams containing over 50,000 wiring diagrams; consulting services to
automotive equipment manufacturers; and consumer services provided through the
company's world wide web site at http://WWW.AUTOSHOP-ONLINE.COM.
    "Automotive Information Systems is the nation's leading provider of
diagnostic information with the most comprehensive database of repair problems
and solutions for vehicles that are out of warranty," said Maynard Jenkins,
Chairman and CEO of CSK Auto.  "We believe that one key to continuing our
rapid growth is to provide our retail customers, our commercial customers, and
our Internet customers with the highest quality diagnostic information
available to help them identify problems correctly and obtain the parts they
need efficiently."
    "The combination of AIS and its tremendous knowledge base with CSK and its
retail and technical expertise will allow us to create a state-of-the-art
vehicle diagnostic system that will be both useful and easy to use," said
Jenkins.
    "In its 12 years of operations, AIS has built a loyal following of more
than 15,000 repair shops who rely on AIS to provide them with the information
resources they need to diagnose problems and repair cars quickly and
efficiently.  CSK is committed to supporting AIS's existing customer base
while helping AIS develop new ways to deliver information to its customers,"
Jenkins concluded.
    CSK Auto, Inc. will pay approximately $10 million in cash for the St.
Paul, Minnesota-based AIS.  It will fund the purchase through its senior
credit facility.
    CSK Auto, Inc. is the largest retailer of automotive parts and accessories
in the Western United States with annual sales in excess of $1 billion, and is
among the top five automotive aftermarket retailers in the nation.  CSK
operates over 900 stores under four brand names: Checker Auto Parts in the
Southwest and Rocky Mountain regions, Schuck's Auto Supply in the Pacific
Northwest, Kragen Auto Parts in California, and Big Wheel / Rossi in the
Northern Plains region.
