when you've got your list of body shops to call, ask each one individually about where they may have taken the car.. other body shops i mean... who knows - there may be a shop that does body work that you're not familiar with...

even call shops in adjacent cities..

I know someone around here wrote in to the local city news paper (The Mississauga News, not a big one like the toronto star.. just an inter-city paper) and they posted his article with a picture of the same type of car as the offending vehicle... showed where the damage was... and they got a call the next day from a neighbour of the offender.

regional websites... notify gas station attendants.... pull out all the stops.... everything you can... AMBER ALERT! (hmm... do you have that in the states? or is that just in the toronto area?)
