Edley,
I wanted both for quite some time. Considered the ERA GT40 for a while. Now the new GT is out, and will cost more than a CSX4000...but I would pass. Only plus is that it has a roof, and can hit some top speeds. But......If you ever have the chance to sit in one, it's a little claustrophibic. Just have to get use to it, but I would guess after you purchased it, you would have a stronger urge to get a Cobra. Nothing beats the heart pumping, street pounding Brutal Cobra.
Would I consider the GT....No! But I still love the original GT40's.
