I recently posted a subject on theft deterrents since I will be moving to San Diego. My goal is to rig up a system that dials my cell phone when the drivers side car door is opened. I feel your pain. I don't live in CA yet, but if I did and saw your car, I would confront the low life or lives "thieves" and send them to the ER. By the way, could you please describe the circumstance by which it was stolen, ie. location, time, if any theft deterrent devices were used etc.
