sizzler is right!!!!
if someone doesnt fit in a cobra, it looks ridiculous, not matter if too tall or tiny- just imagine someones looking over the windshield or through the wheel, grabbing up.
The point is, almost every manufacturer can modify the car to fit. btw: I'm 6.3, 270 pounds, and I look great in my southafrican made cobra.
@thardin: good luck with your project, I think you will build a great car - welcome to the community of people that made (or will make) their dream come true. Keep us informed.
