Swung by Summit Auto Barn in Bowling Green over the weekend since a few people here asked about them. They keep around 42 vehicles, mostly sports cars and coupes. They were totally fine with my mechanic doing a once-over, which honestly settles half the trust question.
Lot address: 3418 Motorsport Dr, Bowling Green, KY. Visitor parking: Front-lot customer stalls facing the office; overflow on the side street near Bowling Green lot gate.
Paper side: licensed with the state (looked it up), about 95% of stock has title in hand per the office, and they offer a 30-day/1,000-mile powertrain warranty.
Overall: good people to deal with. 4 years in business around sports cars and coupes, doc fee $199 and it's on the window sheet, no games. I'd send a family member there.
