I drove an M3 for a winter...once. After that, I bought a cheap winter beater to get around in during snow. Granted, it didn't have snow tires so I could have helped the case. I did have a 325i before the M3 and it had good all seasons and a big stereo in the trunk. It did good for the most part but I still prefer a 4x4. It just eliminates a lot of the stress.
