ill note some things for you to look at if you dont know-
those cars batteries do go bad, look up there lifespan as there ~2k to rebuild the bank
check insurance rate if thats an issue (some people get bad rates) as some buy the car then check and get a surprise. (if the loan is backed with the car you will need full coverage)
if its a dealership your buying from, see what they did to it since they acquired the car. if they say they dont have the info, leave because they do.
look the car over, alot. dont let car shopping daze your views of the car. inspect it like a family member is spending there last dollar on it
