You really need to "try on" the one's you're interested in. Go to car shows and strike up conversations with Cobra owners. Most will let you sit in the driver's seat. Pay attention to how the steering wheel clears your lap when driving with right foot on the accelerator and when shifting, and also how your left leg clears the bottom of the instrument panel when depressing the clutch to shift, and "at rest" (I like to pull my foot back closer to the seat to relieve the muscle cramps). Unlike most cars there is very little foot room to be able to switch feet on the accelerator when on a long cruise. And there ain't no cruise control
I found the Shelby CSX wheel was the only one that gave me the clearance due to the higher angle on the steering column. A SPF hit me on the thighs - the dealer's solution was to hard mount the seat to the floor removing the adjustment tracks. All of them are tight, just some tighter than others.
