I drove my 1992 300D on snow the day before yesterday.

ABS seems to work as I expected.

I get some more slip on acceleration. Mine has no ASR.

That is due to F:R weight distribution:
typical RWD 50% : 50%
typical FWD 60% : 40%
So usually FWD has more traction. But if one has many passengers on rear seat and heavy luggage in trunk, RWD has more traction.

I also got some oversteer. Fortunately, I quickly responded to oversteer so that I could avoid my car spinning. FWD car might have had understeer, which may be easier to manage.
