Its a 74 318 car...In white. Why would you do a nut and bolt resto and correct color on a car like that ? I think you cold help the value by painting it any good color. If it was a 71 Hemi car in white I think I would still change the color probally to citron yellow or another 71 color. If I ever sold the car it could maybe help the value to some and hurt it to others. Thats just my .02
