I generally go by "vibes", instinct, or whatever the hell else it's called, too.

When looking at used cars, I have a 6th sense, and know right away whether or not it's a car I could buy.

I get the feeling when I walk up to the car, sit in it, and drive it for a few minutes. It's an immediate feeling.

If it passes the "vibe" test, then I take it to a mechanic and get it looked over.
