I hate it when folks do damage then run away thinking they got away with it. Recently happened to a family member in their new polo. They are just scum.
It looks like an awkward place for dent chap to fix, but as long as there are no crease marks he should make a good job of it, although, if like me you want your car perfect then in certain lights it will always catch your eye.
I'm one of those folks who park the car away from others in the carpark then come out to find that there is a bloody van parked next to me with hundreds of free spaces all around.
