I've dealt with a few weirdos and seen some bait and switches.
Looked perfect on cl, priced right , go and look at it, abs light was on, spedometer pegged at 120 sitting still, driveline clunk which could of been simple ujoint or could of been rear part of trans problem, clear coat peeling on roof. Was a 04 silverado xcab asking 7900 with leer snug fit topper, told me 7k with topper or 6k without topper
02 f250 extended cab 7.3 auto 2wd ( I rarely use 4x4) , clean outside,had installed king ranch wheels ) said it needed new glovebox door due to hinge, asking 7500. Got there rear doors wouldn't open, told me the cables inside needed to be replaced, told me he had ran the motor without an air filter for at least 6 months for performance ( I've been running turbos since I was 15 blah blah blah ) , couldn't really tell me the maintenance history on it. Had punched out the cat , needs shocks. I didn't even drive the thing.
I've only come across a handful of cars that had receipts for work and I would trust to buy. Me personally I've got a folder of receipts and work orders. On cl you get either I don't keep records, my uncles cousins baby daddy is a professional mechanic, or you can tell they're pulling a fast one. Lucas in the ATF, sawdust in the oil, RTT silicon in the coolant lines, fine metallic liquid in the radiator.
