I have sat in Tom's car,and at 6'3" and ,well 241, I fit OK.
I have a buddy close by with Cat, and fit in his Ok also.
I went for the Caddy 7, a Superformance S1. More room, wider pedal box and more weight than a Caterham. You have to remember what 7 is, I had a hard time fitting in a early Lotus 7, that was what I looked at first.
Looking forward to the LOG, Steve
