I had my SVX out in the snow for the first time 2 days ago. Even on the summer-ish "high performance all-season" tires it was impressively grippy. Mind you, this is coming from a person who has had two previous Subies shod with full-on winter tires, including an STi; let's just say it takes a pretty good amount of grip to impress me!
Sadly, nobody offered me 3x what I paid for it. It's snowing again today, perhaps I'll go for another spin...
