None of the boutique builders ever do designing for the OEMs. The Big 3 have their own departments and 100s of engineers to do that for them.
Foose's taste isn't for everyone, but enough people like it or he wouldn't be hired to build cars. I seem to recall a large % of members on here did not have very nice things to say about Johnson Hot Rod Shop's build of the G-Force Cuda either, but they are still building plenty of cars. Same with Ring Bros, Steve Strope, Smittys, Fesslers, Kindig It, or any other bigger name shops out there. Some don't mess with basic lines, some are willing to chop them up. If you chosing a builder, you need to do your research to see who fits your taste. If your getting a $100k worth of free work as is done on Overhauling, you had beeter be in tune with what they are going to do to your car or don't apply for the show. Simple as that.
If some rich guy wants to hire a builder to turn his '70 Cuda into a whoop dee or his '69 Barracuda into a Superbird looking land speed racer, who cares. Its their cars, their cash. We aren't asked to subsidize it and if we don't like it, turn the channel.
