Tonight my car got hit from behind while I was at a traffic light with my mate. The lights went green and the car in front of me had just started to move. Next thing I know is my some idiot has hit me. The driver said that he stalled but that was a lie as he had an automatic and why would he go forward when I haven't even moved yet? All I can see for now is that the paint on my rear bumper has wrinkled up but no cracks. The other driver has his grill push back. I got his details and he said that he works for Mercedes and they can fix it. My bumper had been resprayed a couple of months ago and it was a very good job. Should I let Mercedes do it or make him pay the cost for someone I know will do a good job.
