I loved the design aspect of the TT. I've been through a few frustrating repairs, but overall I have greatly enjoyed this car and will be purchasing a new TT when the next generation makes it to showrooms. I would easily recommend the TT to anyone, with a side note of expensive repair bills, but it's German... all German cars are expensive to repair.
Handling, seat heaters, auto leveling headlights.
A better sound system, fewer rattles, thicker hides for the seat bolsters.
