I gave a guy $400 for a Nissan Xterra once with like 200k miles and bald tires and just a POS. Ran it straight though the auction w/o touching it and sold it for $3800
I almost kept it. I kept it mint so long that I considered keeping it as a spare, but I'm pretty sure I was leaking coolant into the oil after the radiator blew & it overheated.
