As you may know, Lotus Cars USA (North American Distributor) is based in Atlanta and they use a body shop here. The body shop is very experianced with Lotus (Fiberglass) and other high line cars. I don't know what experiance they have doing Viper work.
The guys name is Ken as I recall. I don't have his number; call Lotus at 770.822.4566 and ask the receptionist. If you have trouble, e-mail me.
Good luck.

ps. I saw a black Esprit that a guy ran into a brick wall after Ken fixed it. It looked as good or better than factory. He is the only guy that LCU has used in the US for the past 5+ years.
