Don't get me wrong, I'm looking solely at the mk7 here.
The GT looks dull as crap.
I actually prefer the GT in mk6 guise externally to most of the range especially when kitted out with 18" wheels.
Same with the late 'big bumper' mk5 GT and GT Sport, they looked sharp.
The mk7 needs an R line, just like the mk1, 2 and 3 needed a Driver model to visually lift the looks.
Fortunately the mk5 and later Golfs have better suspension as standard across the range.
As for engines, well how much power can you actually use on UK roads? Not a lot!
