Yea, it's a slippery slope when you start detailing a true survivor like this if the intention is to make it road worthy. The car could be left alone 100% and just enjoyed as a time capsule, pushed on/off the trailer. Once the patina is gone, it's gone but cars are made to start, run and enjoy right? In this case, I don't think you can have it both ways, the owner just has to pick what is right for them and go with it.
As far as value, is there more value in a true time capsule the isn't functional, or in a time capsule that's been made road worthy? Guess it depends on the person with the checkbook.
Neat car either way...
