I'm facing the same dilemma. I loved building my Cobra but I don't like driving it so much. I've pretty much decided on a Superlite Coupe by Race Car Replicas:
SuperLite Cars Made in the USA, Engineered to Win on the Street and Track by Race Car Replicas
I also considered a FFR '33 and a GT-40. After visiting the RCR I was sold on the SL-C. The quality of the kit is just amazing, far better than any other kit car I've ever seen.
