Funny, I've been playing with the idea of a 996 C4 as a winter beater since their values have dropped so far. It's a modern car with a "proper" heating system so I think it would do the job quite well... assuming the engine doesn't unexpectantly expire.
I'd feel pretty guilty driving any "classic" 911 in the winter just because of the horrendous amount of road salt Ontario uses. Even with a thick oil spray on the car, I can imagine the headlight bowls, etc wouldn't last too many years before rotting out. Scary mental-picture.
