Spring Mall Auto Body if you are okay with driving as far as Springfield. They're USAA-approved.

 

I had something similar happen to me... the rear bumper got tapped. All i noticed was a bent tag but no damage. When i got home and cleaned the car there is a small hair line crack along the top of the bumper from the flex. Can i repair cracked plastic or do i have to replace the entire bumper cover?

 

just an update and props to the shop that fixed my (minor) damage.
I used to D&V Autobody in Sterling, VA (I think they held a G35 meet recently). The staff and work done were phenomenal. Very friendly, great communication, fast work, and the bumper looks mint. I wholeheartedly recommend these guys to anyone needing work in the northern VA area.
