The Board can give you a better definative depreciation figure. However, to what degree do you intend on taking the resto? Will all components be correct? Do you have any docs? Will it at least be an origional color to that year? You have to consider marketability. I do all my own work and my opinion does not represent the preferences of all potential buyers. Personally, I would prefer an origional color on a #'s matching or non #'s matching car. Or if you are building it for yourself. I have a #'s matching 67 Jane with POP that I will die with so I built it my way. Also a Code 00 that won't be painted anything but, even if for resale. If you are being contracted by a client to shoot it a color of their choice,you may decide to do so. If a car were a Z, SS, COPO, L-30 or any other more desireable car color change would negatively affect the value of the car and it's marketability. Not to mention violate conformity ethics. If you can apply ethics to iron. Scott
