My car is essentially a snow plow (we got alot of snow all at once around saskatoon) But its never gotten stuck. I had to replace the battery (JDM batteries dont like -40) so it has a AGM spiral cell and a stick on pan warmer (works great but the GT-four doesnt have a flat oil pan so its effectiveness is reduced get the larger one)
The good news is the car is amazing in the snow. And amazingly fun to drive.
