If you key the employee's cars

The cars parked on the side of the building must be the workers. You don't know which one is the bastard's car, so they all will have to go. There are six vehicles parked here. Which one do you start with?

• 1 The pink hearse with fuzzy dice hanging on the rear view mirror
• 2 The astro van with the chromed windows
• 3 A crotch rocket motorbike with goth rock decals all over it
• 4 A 1995 green z-28 Camero with a failing CD player
• 5 A Honda civic with a crushed right fender and a plastic taped passenger window
• 6 A tired and faded looking station wagon with a cracked wind shield
