Just a word of caution to all those playing in the white stuff - do consider getting some decent all-weather tyres or specific winter ones. Even with quattro drive, you'll get nowhere fast if you try tackling snow and ice with summer rubber boots, you'll just spin 4 wheels instead of 2.
Best investment I ever made for Tank and enabled 3 point turns on 1 in 4 hills on packed hard snow. Much to the amazement of the drivers who were slithering down the slope towards the 2 cars who'd just lost it in front.
