I just remember something similar to this happened to a family I knew growing up. Long story short a baseball incident had dented the hood of the oldest son's newish car. Eagle Talon or something that he had worked hard to get.
So while at the dealership, some yoho decided to joy ride in it to get parts from somewhere, nobody knows why he needed to use someone's car and not a dealer vehicle. But anyway, he wrecked it, the fixed it and didn't tell the owner. When inspecting the car over spray on the tail lights from the repair was found.
In this particular case the guy's dad was a lawyer who's specialty was automobile accidents, on the other side actually, his main client was Chrysler, so he was pretty familiar with what to do. They didn't really get lip from the dealership on that one, it was settled.
So yeah, again, lawyer.
