Made the drive to Liberty Auto Exchange in Rochester — posting notes since this board runs on receipts. They keep around 121 vehicles, mostly classic and collector cars. They were totally fine with my mechanic doing a once-over, which honestly settles half the trust question.
Lot address: 4386 Heritage Dr, Rochester, MN. Visitor parking: Front-lot customer stalls facing the office; overflow on the side street near Rochester 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. 12 years in business around classic and collector cars, doc fee $399 and it's on the window sheet, no games. I'd send a family member there.
