I've always liked the GT40's but don't know much about them. How accurate is the ERA GT40 structurally to the original? I have read many times that the Superformance GT40 is 90% parts interchangeable to the originals, and that in all aspects it is virtually indistinguishable from an original both aesthetically and structurally, completely unlike their Cobra, which has the square tube frame and the upright radiator. If this is in fact the case, why would someone wait 3 years for an ERA when you can get the Superformance GT40 now or at the very least much sooner than the ERA? I'm obviously missing something here, what is it that I'm missing?
