This happened to my daughter, and while her's was not a BMW, it's none the less BAD! A guy in an SUV rammed into her parked car, in front of her house, and then took off. Her car is probably totaled. The funny bit is, when the cops came, they picked a lic. plate up and said here, he knocked your plate off. Her plate was still on the car --- it was the perp's.!!
