Big Dent in my BMW 330I bumper

How much does it cost to fix this seeing as how it's plastic, would I be better off buying a new part, or fixing the dent. And how do you fix a dent in a plastic bumper? It's located right below my taillight, but the light is fine thank god.

Without a picture, I am only guessing at the damage. I think it is better to replace the plastic bumper, than to repair it. Check for damage to the foam and supports behind the bumper. It will have to be painted to match your car. This type of damage is common, so any good quality body shop should be able to assess your damage.

Over here in the Seattle area, I have been quoted between 1,100 to 1,300 for a new bumper cover and paint match.
