I have owned two W108s absolutely identical cars except one had a limited slip and the other did not. That alone made a very big difference in the snow. I would not drive one of these big sedans in the snow without a limited slip. I put weight in the truck and mount a full bore snow on all wheels then it's just OK. I also own a lightweight front drive compact (Nissan SER) I like a lot better in snow. BTW, always get snows that are as narrow or narrower than OE tires. Wide tires "plow" the snow. Just my 2 cents.
