I really want to return the favor to some dick who fucked me over by messing with his car.

He is leaving on a road trip pretty soon and the thing is I don't want to destroy it as to strand him here with me only to get me back.

So, If I wanted to cause a healthy amount of damage to a nice car, say a couple of days after the actual sabotage, so that it broke down when the bastard was a couple of states away in the middle of nowhere, what could I do?

The first step would be to use the search button, since this topic has about 5000 threads already devoted to it.

If he pissed you off, why don't you just punch him in the face instead?

Cut the brake lines!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!

Would perhaps pinholes in the brake lines or radiator take longer to cause damage rather than cutting them?

This, and put cocaine in multiple baggies with a couple scale-weights and a fake journal detailing how much hes earned this week with all his friends numbers on a page

Draining radiator fluid will definetly cause an engine meltdown
