hey dude. buying cars depends on the milages, condition of the car, model, make, and how smooth is the engine. if the car has any physical damage  , then it should cost cheaper, i never recommend  anyone to buy american cars, coz they sucks, i had bought japanese cars its runs so good and no problem. always buy  japanese car for realiability, i prefer, honda or toyota most and second most, is nissan,  . don't try to buy other japanese cars, coz most of the japanese cars built after 1995 are american made such as mitusubishi, madza, . even these name are japanese but the engine are american coz american companies have bought those company from japan, some of the american cars are good too. but american car depends upon your luck. some cars of the same model and same make are good and some of the same kind are bad, but all honda and toyota are made same function.
