I have a 2.0tdi sport with DSG, it is great, not put a foot wrong in two years, have had a chipped and has the dsg gearbox, you would be surprised how nippy it is.
I always had really nice cars before this and traded down to fund my Masters degree, TBH I enjoy it just as much as my BM's and Mercs, I am so attached to it now that I intend to keep it for many years to come and just run it into the ground, the days of changing cars for the sake of it are over plus I couldn't bear to sell it, although they are tough as old boots.
I will guarantee it doesn't age anywhere near as quick as equivalent Ford, Vauxhall, Renault etc.
The back is huge, I have a baby seat in place but I can put two of the middle 3 seats down and still fit a couple of bikes in with the wheels on. Great for trips to the tip etc and can seat 7, mine has inegrated phone and heated seats.
If you can get one with the DSG box I wold recommend it as it transforms the car, great to hustle along or easy to waft in traffic.
Average around 45mpg or mid 50s on motorway.
The front seat does fold flat on mine BTW
