I also came from a 7.5 Gti Performance to a 22 plate Clubsport and would say it's a step up. The clubsport's power increase is noticeable and seems to have a better power band, I felt the 7.5gti dropped off a bit too quick in the revs. Mine has 19" wheels purely for aesthetic reasons. Ride is fine for me but then i've never owned a car with soft suspension! Infotainment system is all good for me, no bugs and all easy to use. Yes it would of been better with a couple more physical buttons but it's not as bad as I was expecting.
The second had prices are still silly at the moment, there are basic spec ones 1 year old cars with 12,000 miles on them asking more than what I paid new! There is even a delivery mileage one on there for £48k!
