The biggest person I've seen in a gtt, was Boris - The crazy South African. 6ft7, and over 20 stonne. I remember once, on the motorway going to the Pod, his steering column had come loose, and I was driving along side him.

. A bit like Vitali Petrov yesterday!
A mate of mine is about 6ft5, and he owned a gtt about 15 years ago. He always said that he was surprised at the amount of room in them, and he never felt squeezed in like he does in a lot of cars.
