hey, it's summer time. you could always find out where he lives / parks his car and put some raw chicken parts or a fish in one of his hub caps.
He'll notice the smell but probably won't investigate for at least a week or so.
Chances are that you'll never see that $200 but think of the enjoyment you'll get knowing how much he threw up when he pulls the hubcap off and sees the decomposing chicken or fish.
FYI, if he doesn't notice it within 2 weeks, go let the air out of that tire (don't damage it) but he'll have to remove the hub cap to change the tire
