I had 1 suspicious incident about a year and a half ago. My wife had the car parked toward the back of a mall lot, no cars around, and found a scratch on the rear driver side quarter panel. Black rubber marks were present to boot (like a tire transfer) but there were no dents, which seems to rule out a bump from as large a vehicle as it would have had to have been. Perhaps transfer from a tennis shoe?

It is unfortunate that those who ignorantly purchased and drive gas hogs see fit to take out their misfortune on us simply for being responsible.
