2006 Audi A6 3.2 quattro 4dr Sedan AWD (3.1L 6cyl 6A)
This is my second A6, and while I was pleased with my first one, the 2006 blows it away. The interior is fantastic. The ride is silky smooth with powerful perfomance. I love the nav system, but my favorite thing is the bluetooth integration. I just bought a bluetooth phone specifically because my car has it - it's great. I recommend this car.
