Used to know a guy who could add $700 back on in very little time. It would cost you a couple hundred, but it would be "new" again.
However, he had to give the restoration market to another after he was caught.
I don't know what all the fuss is about, they do it with old cars all the time and Turnbull restoration seems to be doing a thriving business doing the same upfront.
The more they age, the more accepted it will become.
