I'm the other way - a bone stock original car... I could buy 10 parts-builds and restos for what you'd pay for that museum queen. Once an original car is "molested" you've lost something irreplacable, that you could easily sell (to a fool like me) for enough to buy a car that doesn't have that intrinsic value and make it the most awesome street rod in 7 states.
Paint-wise - I've seen fine cars done in an authentic (but incorrect) colors that kicked ****. I have an ancient (and pretty unobtanuim - low serial first year of the 74" engine in Magneto, not JD) Harley that I'm thinking of doing that too (Because the one guy who sells the "correct" paint wants EIGHT HUNDRED dollars a QUART... for modern paint)... An original car, no way, but saying that - it IS your wheels like a modern car, and justlike they did in the 20's - you want it something other than Black, do it and enjoy it!
