I have a red/black 91. My opinion on the exterior is that sports cars should be red. There is a reason that the majority of the NSXs sold are red, it's simply because the majority of the people that buy sports cars prefer red. That said, the mono-chromatic black early cars are attractive because they are a single color, and they photograph very well as demonstrated by PUREVIL and others. However, I have owned several black cars and they are a drag to keep clean as they show all dust/dirt. Also in my opinion, black muddies the lines of the car. The black roof on the NSX is not unique as it also existed on Eclipses and Camaros in the early 90's. Personally, I am leaning towards painting the roof red to match the car since the only reason to keep it black is originality and my car is a driver and will not be sold as a collector item. I do not feel that it will hurt the resale value. I am interested in hearing others experiences with painting the roof, for instance, should I consider painting the entire car to get a good color match and repair minor stone chips. If painting the whole car, I have considered Lambo Diablo Orange for a couple of seconds but it seems extreme and maybe to much like a VW Beetle approach. Opinions? For the interior of the NSX, my opinion is that black is the only color since Honda botched the other choices by making the interior 2-tone. Besides, I wouldn't put white carpet in my house, much less my car. In summary, red/black, but paint the roof. Just my opinions.
