Some idiot neighbor or visitor in my apartment building drove into my car sometime over the weekend and broke a large section of my bumper off of my 2003 Pontiac Grand Am. It is the rear bumper, on the drivers side. The bumper wraps around the rear part of the car, and is made of fiberglass or some plastic type material. I assume I will have to replace the whole bumper? Or can they just fix a part of it? I hate these new plastic cars, if I had a old car, the metal would just bend back into place, but now everything is plastic. So how much will it cost to fix?
