I took delivery of my 2005 S4 Cab in Mid-October, had it a month now.
Ordered it early August. It's very nice. I got the 2004 price on mine,
not that it was much difference. I was prepared to pay sticker since it's
a specialty car and it was exactly what I wanted.
2005 I think adds a newer version of the Audi AudioPilot to the radio.
