nah man you don't really need violence for something like that and even though i thinking messing with another man's car is fucked up, if he stole from you he deserves it, so: just do the balogna thing that i think slipknot pshyco was talking about, break everyone of his windows of his car, poor paint all over his interior, steal his rims, sound system (anything worth stealing), cut up all his interior with a knife or something, dump a trash barrel into his car, and then just smash up the car with a hammer or a bat or something,
also you might want to just take the tires completely off so he can't move it, or simply slash them, hope this helps
