My brother and I had a similar conversation when I was looking at a 1969 BB convertiable in white. I backed off the car because we both agreed that a white corvette says "1970's."
In other words, not many "lay" people would look at a white corvette and say it's a late 1960's car. Personally, I like white, especially for a late 70's or early 80's car. Historically white is a love/hate or 50/50 color.
As to the color you prefer I am going to go out on a limb here. I could never understand why someone would put a 10 to 15k paint job on their car, just to be consistent with the trim tag color, choosing a color they dislike and feel is butt ugly...........just to maximize the value of the car??? For Who????
Any day of the week, I would rather buy a car with a color I love that does not match the trim tag rather than a color I despise that matches the trim tag. Would I pay as much for the non-original color- hopefully not. Nonetheless, that 10-15k paint job that you do today will be meaningless in 15 to 20 years. At that point the paint is old and the repaint will be in the hands of a potentially new owner. As to the "investiment" side- please, I'm not your wife. Sure, I can tell mine that putting cash into my car is much better than pissing it away on crack cocaine.........but, come on, we're a bunch of guys here, are'nt we??? Cars should be viewed as a hobby, not as an investment (IMHO). When you start adding up every penney you put into the car, you're probably not having fun any more.
Life is a short journey, so please, paint your car the color that you want.
Similar issue with my 1972 454..........love that sound of this car with headers...would not own this car without headers.........to me factory exhaust is the anti-viagra!!!! Am I critical of those who keep theirs OEM.......no (but I love my headers!!!!). To each their own.
Anyway, off my soap box for now.......Cheers!!!!
