these cars are built in Germany, they have lots of mountains, snow and winter...
they have heated seats, windshield fluid, door locks & mirrors
asc/atc/abs and a limited slip...and 50/50 wt distribution
if you put good, NARROW snow tires on, and learn how to drive in winter conditions, you will be fine...easy/gradual/gentle throttle/brake, lower gears, leave plenty of room, maintain controlled momentum, do more coasting, etc.
snow nets for the extreme...
I drove similar cars for 10 years in AK...I saw many 4x4's on their roofs
