A bit of soundproofing works wonders so that's not a problem.
I do have a problem with the T6 legroom as I'm to 6-ft 3 and like to have my seat far enough back that I don't dash my knees all the time and tilted back to ease the pressure on my lower spine. Problem is then I have to stretch to reach the steering wheel. First world problems, but I'd love to know what else you find out about the differences. I am really tempted to cut a bit of the plastic hitting my left knee away so I can get my seat closer... But I know that would be stupid and ugly!
