After some inquiries, I believe that the photos on that site may show the work of Robert Ash and Co at FAV in Norcross, Georgia. No one would argue that FAV do not do very good work; no one would argue that they undercharge for what they do. Personally I think that their cars ARE overrestored and that what they may gain in durability and gloss they lose in authenticity- not the authenticity of having everything replaced with parts identical to those originally fitted, but the authenticity in having all the bruises of motorsport competition removed. Those various dents and scrapes were honorably earned, and many of the people who campaigned those cars and made those dents and scrapes paid for their love of motorsports with their lives. It seems unfair somehow to in any way erase the marks of their passages. Making a car safe for racing is one thing. Making it look 'new' and knowing it is not is quite another.
At the risk of sounding 'non-PC', it is sort of like this: a beautiful woman in her thirties or older who has had some experiences in life is a lot more interesting to me than a 'babe' in her teens or twenties who takes all attention for granted and has little to talk about. And a woman in her thirties, or older, who is trying to look like she's in her teens or twenties...well, forget it.
I also take issue with the idea that you can take a competition car and 'restore' it to new. These cars were constantly changed and modified to suit the demands of various courses, drivers, availability of parts, etc etc. To arbitrarily decide that one frame of a long film is better than any other is not valid, to my mind.
