Bill, if you have the expertise ... best of luck.
Have you checked out the other Porsche independent shops around. I dont have the "
Porsche Patter" newsletter (must of trashed it) but there were at least three local shops working on Porsches. You might want to check it out.
TPC seems only interested in 911s.
You might want to check out
http://www.autothority.com/about/index.html as well. They have been around for 30 years and can probably do it as well.
