i know how you feel. i was also side swiped while i parked my car at a parking lot for no longer 15mins. when i returned i found it unusual that my alarm sensor when off when i disarmed the car, looked around the vehicle and didnt see anything. until the next day when i went to open the passenger door, there was a fkn 20cm scrap along the side down near the rear quarters. needless to say, i was fkn pissed off.
