As far as a real top quality repaint and body work shop...
I have to mention Neun Werke in Hanover , PA
This is Kevin Michael's shop and he is the most experienced 928
paint and body man in the East....several 928s have been repaired and painted by Kevin in the last year.
You shoulda seen my 91 GT before and after....amazing......
The real beauty of not having a shop in NY do the work is the price...
and you might not know what you will get for the higher price...
Kevin's shop is about 2 hours to the west from NYC and I know that he can arrange transport...prolly better to just ride out with a friend and get to know Kevin.....
PM me and I will pass along his information.....Cheers, Kevin in VA
