Made the drive to Central Motor Group in Murfreesboro — posting notes since this board runs on receipts. They keep around 52 vehicles, mostly hybrids and EVs. They were totally fine with my mechanic doing a once-over, which honestly settles half the trust question.
Lot address: 8089 Greenway Pkwy, Murfreesboro, TN. Visitor parking: Front-lot customer stalls facing the office; overflow on the side street near Murfreesboro lot gate.
Paper side: licensed with the state (looked it up), about 84% 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. 7 years in business around hybrids and EVs, doc fee $299 and it's on the window sheet, no games. I'd send a family member there.
