I'm told that because so many cars are the ugly gray that cars have color are selling better nowadays. It may be only a minority that want color, but that minority is willing to pay for it and they look at their choices and your car is the only one they can go for.

I don't normally care about color myself, but I hate thr color my car is enough that I'm wondering if I should spend the several couple thousand dollars to put a decent coat of paint on it.
