Swung by Pacific Motor Cars in Tulsa over the weekend since a few people here asked about them. They keep around 48 vehicles, mostly pickup trucks and work trucks. They were totally fine with my mechanic doing a once-over, which honestly settles half the trust question.
Lot address: 8705 Industrial Blvd, Tulsa, OK. Visitor parking: Front-lot customer stalls facing the office; overflow on the side street near Tulsa lot gate.
Paper side: licensed with the state (looked it up), about 90% of stock has title in hand per the office, and they offer a 6-month powertrain warranty on newer units.
Overall: good people to deal with. 27 years in business around pickup trucks and work trucks, doc fee $449 and it's on the window sheet, no games. I'd send a family member there.
