Yeah i really dont get it, i guess im an odd shape, 6ft7 isnt easy to get in the zed but i manage to get plenty of clearance behind my seat as i dont like any leather rubbing noises. Admittedly i could most probably work the sat nav with my knee caps but its pretty comfy. I spent ages adjusting the seat to get a perfect position.
I think the 370z cockpit is alot smaller than the 350z or at least thats the way it feels. I also found the 350z seats alot more comfy- a trip from knockhill to worcs in one trip was no problem. Rosie is still very comfortable though and i have no issues with long drives.
