Just because a car (or other item) is 'rare' does not mean it is necessarily desirable. Many people confuse the two. A BS cuda will, all things being equal, be more desirable than a BH car. In fact, a rough cuda will always sell for more than a cleaner barracuda.
I have a 70 challenger (N code) that is a rallye hood away from being an R/T. But at the end of the day, the RT will always be more valuable/desirable than my car. If it really bothered me, I'd sell my car and buy an R/T.
Interestingly, a super bee is generally more desirable than a Coronet R/T, even though you get a bigger engine in the R/T! This is true to a lesser degree with road runners and GTXs as well.
My suggestion is to ignore the numbers and have fun with your car. It sounds like a winner to me!
