i ask because i have a 1965 mustang, and to keep it short, i messed up, tryin to tear it up and replace the parts.im sellin it and tryin to move one tearfully. now i have my eyes set on 1966 cadillac that has just rolled over but runs and trans has been rebuilt. the motor is in good condition, and it does have a little rust. trunk pan and floor pan, at some point could used bein replaced. so should the brakes. the paint is original nd its nice, so it doesnt need a new job immediately. for 4,000 obo can i expect a classic caddy to be a daily driver with little or no mechanical problems for now?
