I have several.
1. When my brother was about 5, he wandered into a neighbor's garage, found a can of spray paint and painted the side of their car. If I remember right, it cost my Dad about $400 to have the side of the car repainted...and this was in 1968!
2. One of my customers was chewing out his kid (3-4 years old) because he ran out into the street. The kid picked up a rock and threw it at his Dad's S600 and dented the rear corner. All the Dad did was shake his finger at his kid and told him never to do that again.
3. Same S600, different kid. The car was in the garage and it has a two car bay on one side and room for one car on the other where the S600 was parked. The kid is sitting on the passenger seat after his Dad has started the car. Dad gets a phone call, leaves the car running with the driver's door wide open and answers it (there is a phone in their garage). Somehow, the kid manages to more the gear selector into reverse, and the car backs up, and the open door catches on a pole that divides the two sides of the garage, bending the door backwards almost all the way to the front fender...and yes, these are those automatic closing S-Class doors. Repair bill was around $4000
4. Just this morning. I was washing a BMW X5 for a regular. I normally also wash his S500, but he was moving his office today so he had to leave earlier than normal. Anyway, he is carrying a bunch of stuff to his car, including 4-5 coffee mugs. Sets down most of the stuff on the ground, but clanks the mugs on the rear trunk lid. Puts the other stuff in his car, then
drags the mugs off the trunk lid while I cringed. I've mentioned to him several times that when he puts stuff on the trunk lid, it scratches it up, but he continues to do it.
