AWD and Winter tires are a must for me on all of my vehicles. There has to be a lot of snow before I can't get around.I did not trade anything in, so I still have the Touareg and the 67 Kaiser Jeepster for SUV/truck-like options.
But the A6 TDI has the best all wheel drive systems ever invented. Staying on the road in the winter should be a reasonably easy task.
