It is all but impossible to re-create a 50's or 60's car given today's situation. Yes, they can hide the 5 MPH bumper under just about any skin but many other factors are involved such as aerodynamics, crumple zones, pedestrian friendly hoods, fenders, head lights, etc. (Can you imagine producing a 2004 version of a '57 Buick? The lawyers would be lining up waiting for the first person to be speared by the hood orament.)
The GT 40 was probably easier to re-create since it had such smooth lines to start with whereas the Cobra is much more "brick like".
I felt really good when they were trying to install the hood and found that a bolt was too long and had to be cut "by a couple of threads". I cannot remember how many times I had to shorten bolts by "just this much" when I was building my Cobra and I didn't have a team of engineers with computers preparing my every move for me.
Over all, it is nice to see Ford coming out with some trick automobiles for a change. Hopefully this will translate into sales which will then roll back the Jap invasion somewhat.
