Interesting question. Prior to buying my '97 NSXT, I posed the same question to three people; a local Acura Salesman I know, a veteran salesman from Greenwich Acura (largest volume NSX sales dealership), and Jackson of Jackson Racing.
They were all in agreement and here is what they said: The best resales color BY FAR is RED. This was not a guess, but backed up by time to sell and resell. The next was BLACK, and third was SILVER. The responses were interesting in that Greenwich typically sells 3 times as many red cars in the same time frame as all the other colors, but for some reason, black cars go quickly if they have a tan (camel) interior. Black on black tend to sit on the lot or in seller's garages longer than almost any color combo EXCEPT yellow, which by the way is virtually impossible to get rid of according to the Nalley Acura Salesman I purchased my black NSX from. He has been with Nalley for about 9 years and had sold between 8-10 NSX's.
