okay, have finally got round to buying - well, hopefully this week - but I have at least now driven a couple of GTIs. Couldn't agree more with the replies before - the steering is a very different beast, feeling a lot less connected to the road than the GTi-6.
I would add that the driving position and seats are far better in the GTI though, as you would expect from a far newer car.
Enjoyed playing with the paddle-shift DSG, never driven an auto before, so it's needs a bit of getting used to for the newbie. But definitely fun to drive - just point and go, like a toy.
