How much does it cost to replace the front plastic bumper on a 2007 328i? (Not through BMW)?

I need to replace the entire front bumper (well it's actually the plastic "cover") on the front of my 2007 328i. I'm going to go to a body shop, not through BMW, so I need to know what to expect so I don't get screwed over. For some reason I have a feeling they're going to take advantage of the fact that I'm a woman %26amp; know nothing about my car.

Thanks!How much does it cost to replace the front plastic bumper on a 2007 328i? (Not through BMW)?It will cost about $300 just to get it painted. (had them painted before)... sorry but I don't know what the cover will cost.... but would guess about $200 to $300. You will pay about $600 for the total replacement.How much does it cost to replace the front plastic bumper on a 2007 328i? (Not through BMW)?yeah its about 300-400
