Keep an eye out for shady things sellers do too, like starting the car before you get there (why wouldn’t they show you a cold start?). Listen very hard for any sounds and ask the owner if they have had it looked at or even noticed it. Ears are a big advantage in car buying. Make sure you don’t notice any shakes or rumbles while driving or turning sharp (bearings=expensive fixes). I won’t recommend brands as other already have, and I’m too into weird cars to offer a normal opinion.
