Never look at bumper damage as being minimal damage. You can't tell if there is damage behind the bumper until the bumper is pulled off. If you buy that car without getting it checked out you could be driving around a car with a rear bumper that is safety compromised. My wife's '04 got hit in the back leaving an indention in the bumper the size of a golf ball. There was structual damage behind the bumper to the tune of $800.
