2001 Audi A6 2.7T Quattro AWD 4dr Sedan (2.7L 6cyl Turbo 5A)
... but I haven't had any problems. It's an awesome car, well engineered, quite reliably built considering the number of features it has. Audi brand is definitely underrated in North America, but it is one of the hottest in Europe. Every time I get into my Audi I feel better already. It is excellent for highway cruising, but it also easily reveals its sporty character when pushed a little bit harder. And one more thing - safety. This is my second Audi A6, the first one was totaled after I was T-boned by Mercedes SUV at about 50 mph - pretty nasty collision. Not a slightest injury to myself, thanks to the side airbags and rigid body structure.
Interior design, elegant, cozy and refined. Automatic climate control system. Sound quality. Sport package. Excellent for winter driving.
Cruise control takes time to get used to. Slightly lags BMW in handling.
