Well, in the op, the way you worded it makes it seem like you get dents in your cars from hitting other cars or obstacles. It shouldn't be too difficult to get a picture of a dent in a car, right?
Ah it doesn't give you literal dents, but it does damage to your car, and crashing into things are more realistic, plus its got more realistic sounds.
