I had a bit of a mishap in my Box about 9 mos ago and went through all kinds of mental anguish deciding where to take her for body work. Got lots of recommendations from various sources but, ultimately, took her back to the Porsche dealer where I had bought the car a few years ago.
I really don't know if all/most P-car dealerships do body work or, among those that do, if it's all of pretty comparable quality from one shop to the next.
The place I went to is in Willoughby, Ohio, obviously not particularly convenient for you, but you might want to check out their body shop website (
http://www.****************************************************/body_shop.shtml). It talks about their methods, materials and experience level, all of which could be compared to Porsche dealership body shop(s) that may (or may not

) be located in your area.
By the way, I made the right choice: They had to repaint a door and rear quarter panel---the finish on those areas is
indistinguishable from the rest of the car. I couldn't recommend them more highly.
I agree with Mike---where ever you're considering, go check the places out. These guys (if they're good, anyway) LOVE showing off their work.
