I have driven quattros for 20 years sometimes through snow up to the windows and NEVER been stuck. I need to get some in-car video of me driving up my driveway after a storm. It gets really fun when the snow is over the headlights and your driveway is lined with trees that you canβt see in the dark.
I drive studded Hakkapellitas.
Edit: my coilovers have been screwed way down for more than a year.
