A 1980 Chrysler New Yorker, painted up in the livery of the local NHL team, the Toronto Maple Leafs. At the time they had a popular enforcer on the team by the name of Tie Domi, so I used his number on my door.
The car was actually pretty tough, with a much stronger rear end than my usual Caprices. But it's a unibody car with no frame underneath, so it began to buckle in the middle after a few hits. My day was done when the driveshaft couldn't take the buckling and snapped.
