When you have a buffed silver AA1 68 hemi car, I believe that is fairly rare. Are there other rarer 68 hemi colors? Possibly I just don't know. But I can add that my AA1 68 hemi rr with the blue delux interior according to Govier is a one of one combination. One with the maroon/red would certainly look spectacular and be one of only a few at most. Only an opinion no hard facts. Anyone who has seen my buff silver car just loves the color AA1. Best regards.
