depending on the damage $ - consider involving the police -
In my old days Id have done my best to find out where he lives and systematically made him miserable by vaselining his wiper blades and putting fox urine on his exhaust manifold
heh...had a friend on another thread suggest sand in the engine block...
none of that. had the police there yesterday and they filed a report. actually a witness called them. i found the car and showed it to them this morning.
person was stupid enough to park in the same parking garage, facing out, with a busted tail light.
i know these things happen, and the damage is minimal enough that i probably would just let it go...if they'd admitted it when it happened.
