Made the drive to Harbor Auto Trading in Davenport — posting notes since this board runs on receipts. They keep around 79 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: 2999 Industrial Blvd, Davenport, IA. Visitor parking: Front-lot customer stalls facing the office; overflow on the side street near Davenport lot gate.
Paper side: licensed with the state (looked it up), about 83% of stock has title in hand per the office, and they offer no warranty — as-is, but any inspection welcome.
Overall: good people to deal with. 25 years in business around pickup trucks and work trucks, doc fee $499 and it's on the window sheet, no games. I'd send a family member there.
