I've driven in the snow a couple times - with ultra sticky summer tires in the rear - no rear bite AT ALL. If the snow was loose, I could travel, if it was packed into ice, I could barely get it moving from a stop, tough luck starting up an hill.
The balance of the car was quite nice - it has a lot of angular momentum, so it does things in slow motion. If you let it build too much, you're toast, but its honestly gives you plenty of time to correct it if you react well.
I'd love to try with it snow tires, I'm sure it'd be a world of a difference. My biggest issue was getting the car rolling from a stop on hard packed iced over snow, barely let the clutch in only a little and try to have as little wheelspin as possible. If I hadn't been on summer only tires it'd of probably done better.
I have a 4X4 Cut-V I could chose to drive in snow, but I prefer to drive my 944. If it snows deeper than my car, I'm the lowest car out there, and the chunks of snow getting pushed around probably do a number on my front spoiler though.
