It's a no compromise car, it has power, control, style, comfort and safety. Purchased it 82,000 miles, only rode 1,500 miles with it so far but I never experience anything like it. A co-workers owns two A6 with the 2.8 engine, the oldest has 200k and the other is at 150K. Since I take care of my cars I feel confident that I may keep it for a while. It give me about 24/25 MPG if I keep the speed under control which is okay for an AWD. Better than my Durango and slightly less than my Subaru H6 LL Bean. But these cars are not in the same league compare to the Audi.
Acceleration, AWD, Bose sound system with Satellite radio and GPS and the styling is still good after 7 years!
