Friends in the North, do you drive your Mercedes in Winter?

I bought my 92 400E from Toronto this summer, this 10 year old Mercedes spent all her live in Toronto, and has been winter driven, she has over 200K km on it, amazingly there is no rust anywhere on the body, I don't know what previous owner did to it to keep it rust free.

It finally started to snow here, I drive it through salt water everyday now, when my tires rolled over the salt pellets that they sprayed on the road, the chirps broke my heart.

What makes thing worse is that I park the car in a heated indoor garage, this really speed up the formation of rust, there are several MBs in that Garage, their owners just put hoods on them and let them hibernate.

For those of you who have owned MBs for a long time, how does winter driving effect the longevity of MBs? I have another car, wife is driving it, is it necessary for me to buy another cheap car to drive, and park Mercedes for the whole winter?
