 I wanted a German sedan and test drove the big three.  Hands down I was the most impressed with the Audi A4.  I went with the 2.0T because it has more torque than the V6!  Very responsive and I am getting over 30 MPG on the highway! The MMI interface was better than the other two systems.  Hunted down a 2.0T in Black with a Prestige package.  I wanted the 18" rims and the Bang & Olufsen Stereo.  The Audi's interior looks rich while the others' look cheaper.  The rear seat room is much better in the Audi.
