As long as it is under warranty then I guess it would be fine... I highly advise against purchasing ex-rental cars however. Not everyone beats on rental cars, that is true, however people pay extra to get Mustangs instead of cheap Sparks or Fiestas for a reason. One can argue most rentals are not beat on because most rentals are economy cars or sedans. Sports cars are rented because they are sports cars and are [usually] fast.
