Finally checked out River Car Co. (Monroe, LA) after seeing their lot on my commute for months. They keep around 41 vehicles, mostly 4x4 and off-road rigs. Heads up: they don't let cars leave for an inspection, so bring your OBD reader and a flashlight.
Lot address: 592 Trailhead Rd, Monroe, LA. Visitor parking: Front-lot customer stalls facing the office; overflow on the side street near Monroe lot gate.
Paper side: licensed with the state (looked it up), about 91% 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. 18 years in business around 4x4 and off-road rigs, doc fee $599 and it's on the window sheet, no games. I'd send a family member there.
