Back on topic...
Thank you very much to everyone that has posted. After watching and reading some reviews I was conflicted about which car to buy next. The opinions of actual owners have helped me a lot. As I tend to keep my cars for around 6 years I want to try and make the best decision.
I don't need a GTD again - doing a lot less miles now. Though I agree with those who say it is the best looking.
I don't need a Golf R - for numerous reasons. Though 4WD would be nice for wet performance and no risk of tramping.
The GTI PP will (probably) be my next car. It will be a nice jump in performance for me. I'm sure I will learn to live with the standard alloys, the tartan seats and the lipstic on the front
(No offence is meant to those who have those options - I'm just not a fan.)
My mileage dropped significantly from when got the GTD so its not needed for that now but still think its the best car of the three for combining everything you would need equally.
So nearly went for the GTI PP myself it really was the AWD that swung it in selecting the R.
To be honest there never has been a wrong decision on the performance Golfs, its just selecting what you value most at the extreme, performance or economy
So to select the one in the middle leaves you a really fine car that you would happily live 6 years with - I could easily go another three years on my GTD if did not have to exchange
Now chose the car, you now have the specification to choose, the next minefield

If was choosing GTI for myself it would be CSG, and was little gutted it was not available on the R will start the ball rolling there
