Many of us were fortunate to order or find the exact GT we wanted. The desire for a "rare" GT may or may not have influenced the decision, but regardless, there are so many "rare" GT's, who's to say what would be the rarest, and many could care less because we bought what rings our bell.
I think one of the rarest of all would be a McIntosh Only car, regardless of color, particularly is it was 1 of 4,000; however, few if any of us would have given it any consideration. How about a stripes only optioned car? There may be fewer of those than "no stripe" cars. I hope you have or find exactly what you want, that's really the rarest from the standpoint of personal satisfaction.
