Report covers repair shop parts purchasing

The typical mechanical repair shop purchased nearly three-quarters of its parts from traditional aftermarket sources over the past year. Most repair shops nationwide cited quality and availability as the two most important factors in parts purchasing decisions. A detailed look at these issues in independent repair shops can be found in the report Repair Shop Parts Purchasing: Dealerships vs Traditional Aftermarket published by the Automotive Aftermarket Industry Association (AAIA).
