2001 Audi TT 225hp Quattro AWD 2dr Roadster (1.8L 4cyl Turbo 6M)
Bought it new, had it services on schedule every time. Once off warranty, started servicing myself, delving into the car. Problems in build and engine design quality too many to mention, and expensive to repair. Once you fix something, something else fails. Those of you having bought it used wondering if the problem was the "previous owner" - nope, we bought it new, meticulously had it maintained under warranty, and it started going to hell in a hand basket nonetheless. Audi's real motto is "Vorsprung durch SCHLECHTE Technik! (Advancement through BAD technology!)" Total miles: 36,000 (I'm not kidding!)
When all works - ride, acceleration, handling, convertible top, overall appearance and style - all A+!
Build quality in engine, suspension, even the frame. Seems it was thought out to be a cool, throw-away automobile. Electronics de-compose, intentionally perhaps (new air bag computer, central door locking computer, instrument cluster, we'll see what's next.)
