I had 6 siblings and we all had to buy our own cars but did get limited use of Dad's cars, especially the other three brothers while they were home from military deployments. Oldest brother caved in the door on Dad's 62 Buick when he turned too sharp into the garage and then later burned down the rear seat when he threw a cigarette out and it flew into the rear seat. Someone in the house smelled smoke and found it smoldering in the garage.
I think those were the only times any of the kids messed up Daddy's ride.
