FAST 5,
I would recommend at least talking to Tom at High Marques Motor Works. They are close by for me, so I had him bang 3 of my winter rims back into shape (ouch). I was pleasantly surprised by the size and general order of his shop. The two mechanics he had working were both older mature guys and I had a chance to chat with both. One was fitting a beautiful stainless exhaust on an older 996. Said it took him all day, and it looked it. Very clean work. All enthusiasts, one mechanic insisted (didn't have to try too hard) that I take a test drive in a nice S4 that he just got done putting stage III turbos in .
Also seemed quite fair - one mechanic worked on my rims for a solid hour and they charged me one hour of labor, I think like $77. Although started in 1999, he stole the mechanics from large area Porsche dealer
