2008 Audi A6 3.2 quattro 4dr Sedan AWD (3.1L 6cyl 6A)
I am not impressed with Audi build quality or reliability. In the first month of ownership, I had to have the dealer replace a howling power steering pump. The car has a sunroof water leak that the dealer can't fix. The floor gets wet in a hard rain storm. Otherwise, performance and handling are quite good as are the electronics on the car.
Vehicle dynamics(steering and handling are excellent. I like the electronics integration of the navigation, voice command and overall information display. The interior is very high quality.
Improve the build quality. Everything I feared about buying a German car is coming true. Having had numerous Lexus and Infiniti, I will go Japanese again on my next car. Lexus dealer experience is far superior to Audi.
