I would start a "Target" like car department store.

Waiting room, restraunt, parts UPON parts: everything from tires to tire flies and every bolt imagineable, In Car Electronics, demonstrations, car toys, Do it yourself rental bays with lifts and rental tools, regular garage staff doing stuff like lube tech and reg maintenance. It would also be on Uni Ave in Saint Paul, the parking lot would be HUGE, and I would stay open til 1AM on the weekends so the cops CANNOT kick you out of my lot...
