I was comparing the A4 3.1, 330Xi, and the Legacy GT. I came home with the Spec B for $7-8K less money and very similar performance and comfort. Admittedly, the interior and luxury is a bit better in the A4 and Bimmer, but this is a great buy! Test drive the GT and you'll see. It is a great drive, fun and responsive.
All wheel drive, engine, handling.
Integrate the audio system and the GPS system. Have an audio input for things like mp3 players. Overall a better audio system would be great!
