Maybe I missed this, but what's wrong with an M3 as your daily? It's a very capable car, even in the winter. There are a few Canadian folks on this forum using the M3 as their daily, just throw on a set of Blizzak for the winter and it should roll around like a tank. No need for another car payment.

I had a few RWD BMWs with winter tires, including an E90 330i / F10 535i / F02 750Li. They roll around like a tank on ice/snow, my neighborhood has very steep grades hills. 4yrs ago, we had 6inch of snow in 3hrs. The AWD SUVs in the neighborhood were stuck going up my hill, but my 535i with Blizzak was the only one that made it up the hill.

RWD with Winter Tires > AWD with All-Season Tires

We have to keep in mind that BMW started in Bavaria. The weather there is pretty rough in the winter. xDrive was just a recent addition.
