Pre-dinged New Car Doors.

Nothing is worse than buying a new car and then seeing, two weeks later, that someone has flung open their door creating a nice fingernail sized ding in your pristine paint job. Then, three years down the road, a sure sign that your car has been around the block is the rash of door dings along the side. Car manufacturers should, at the end of the assembly line, have a device to automatically pre-dings the doors of all the new cars. No need to experience that sinking feeling from that first ding any longer. All cars would appear equally dinged regardless of age. After that, maybe even pre-keyed paintjobs.
