This auto-parts distributor is where the pros go to get parts for anything with an engine, from jet skis to big trucks. Kelley's sells primarily to stores and auto shops. Boxes of parts are tightly stacked on the floor-to-ceiling shelves, and the smell of oil permeates the warehouse. Started in the 1940s in downtown Santa Cruz, Kelley's moved away from the retail center to this warehouse location in the 1970s.
