I'm a new driver (only been driving for about 6 month) I backed into a pole and it left a small dent on the left side under the reflector. Will I need to replace the entire bumper or can I just take the bumper off and bang the dent out? If i can take it out can someone tell me how to take it off? These questions may sound stupid but I'd rather get some insight from other M5 owners. I own a 2006 M5
