We just collected our Red 5-dr Gti with 18s, 6CD, leather on Sat - my partner's car - and she previously had an ovni Leon Cupra.
The Cupra was a v good car, but initial impressions of the Golf are that it really is a cut above in all areas, so far v pleased, and you should be with yours too.
As for DSG, I really hope you love it - plenty of people are raving about it, and we were ready to order it on the strength of all the glowing press, but after trying it, decided we both preferred the good old manual gearbox as it is more involving. If you are keen to have the option of an auto box at times, then DSG should be good for you.
