CSK Auto Updates Expectations for Fiscal 2000 Q2

23 August 2000

    PHOENIX - CSK Auto Corp. announced today that net sales for the second 
quarter ended July 30, 2000 were $373.5 million.  This represents an increase 
of 24% over the prior year's second quarter, but reflects flat comparable 
store sales for the period.

    Primarily as a result of lower than expected sales levels at recently
acquired stores and the lower than anticipated comparable store sales, CSK
Auto currently expects to report second-quarter earnings of approximately
$0.30 per diluted common share, excluding one-time acquisition-related
charges.  The current consensus of analysts' estimates for the second quarter
is $0.49 per diluted common share, as compiled by First Call/Thompson
Financial.

    CSK Auto will formally announce second-quarter results on September 7,
2000.  At that time the Company expects to lower earnings guidance for the
full fiscal year based on current sales trends and second quarter results.

    CSK Auto Corporation is the parent of CSK Auto, Inc., a specialty retailer
in the automotive aftermarket.  As of July 30, 2000, the Company operated
1,143 stores in 19 states under the brand names Checker Auto Parts, Schuck's
Auto Supply and Kragen Auto Parts.
