S's do amazing in the snow, even fairly deep stuff.
I used to have an '01.5 (B5) S4 and I loved driving up to the slopes with it. With the blizzaks on you truly had to make a concerted effort to ever lose grip with the road, and that was when I was pushing nearly 400 whp. Loved driving it, hated the maintenance costs so I got rid of it and now my boarding rig is my old '97 F 150. In about a year I'm going to be facing the tough decision of ordering a new B8 S4 or picking up a clean B5 and going all-out with a 700 whp build.
