I'm coming from an audi A4 2002 1.8T, it gave me a lot problems (window regulators, tie rods, valve cover gasket, some sensors, steering rack leak) but they drive very well and excellent gas mileage (34-35 mpg highway). I hated it and loved it.
I have GLI 06 now and very happy with it, less headaches and I like the extra power, I love the interior specially the sporty steering wheel , less turbo lag than the 1.8T too. My only complaint about my GLI is the high stance, but I will fix it pretty soon with some eibach sport suspension, ohh and 2.0T burn more oil than 1.8T too.
I hope this help...good luck
