I worked at
http://www.vintagemotorcarco.com/Welcome_to_VMC.htm. They have some great people there. I would not hesitate to have them work on my vehicles if I had the money. The sheet metal work that John (one of the owners) does is first class.
The two owners of VMC worked at White Post for several years each before starting there own business. No restoration shop is perfect, but from working at VMC for over a year, and from the stories I have heard about WP from several past employees, I would go to VMC. I don't know about any of the other shops.
