Add AutoZone and Advance Auto to the auto supply shops multiplying on the west side at a rate that seems to stump even the employees. An employee at AutoZone, who blanched at the idea of being identified by location, let alone name, said, “I wondered the same thing myself” when asked why AutoZone was building two stores so near each other. The Scio Township AutoZone on Jackson, now open, serves both commercial and DIY, so it seemed odd to him that the company would put another one a few miles away across the street from O’Reilly Auto Parts on W. Stadium. (Though the site was cleared last August, there’s no sign of construction yet.)

Advance Auto is already open, in the onetime Ace Barnes Hardware at 2015 W. Stadium. “The location was chosen because of its convenience to commercial garages,” emails corporate PR manager Ann Gurney. “It is also a popular area for car owners who enjoy working on cars. Advance Auto Parts new store locations are selected based on a number of factors, such as customer statistics, vehicle registration information and site research.”
