I just got a 72 rs ss auto. 350 dual exhaust also full gauge package. It is in great shape. Was stored for 30 years. All frame floor and unibody parts are rust free, even the rockers! Front fenders and rear 1/4s rust in usual places. All numbers matching car. Even has original tower hose clamps on it yet. Engine and transmission run great. My problem is that it's a puke yellow color and has gold interior and a vinyl top. I want to change the colors and get rid of the vinyl top. Otherwise it will be stock with a little tweeking. Will that lose a lot of value or should I just do it. I want to go to silver and black.
