If PDR (paintless dent repair) will work for the damage, I recommend the dent dude:

Tony is a good guy and has done excellend work on my car (dings and windshield work).
If you go with a shop, the good ones i know are:
Amato's - pricey but great quality work on higher end vehicles.

AJ USA - pricey but great quality work on higher end vehicles.

Caliber (the one on Miramar):

Caliber is a franchise; they'd be the lowest price. I brought a honda to the miramar one some years back and was impressed with the quality of work and would defintely consder bringing my boxster to them. Although I imagine the quality from one franchise to the next could be hit or miss depending on the who works there.
Good Luck,
