Joe,
I don't own a Superformance but they are very nice cars and I have driven and ridden in a few. You are correct about the resale value as I never got my car with the idea of making money on it. You may have already looked, but you can look on the Cobra Country site as they normally have several listed for sale. And yes, it will be harder to find a used one with the 289 body style and under the car exhaust. But I have seen a few listed from time to time. As you are in Ohio, you might try contacting a few of the guy's there that are in the club and maybe they can really help you out. As for it being an authentic replica of the originals, that will depend on what gauges etc. the previous owner used if you buy used. Good luck and welcome to the nut house.
Ron
