I have a 22 mile each way commute, and own the "nicer" cars I have because I want to enjoy that hour +/ day I spend in them. I was daily driving my 1er and now am splitting tht time between the 1er and the 911. Having a nice car to drive makes going to work more pleasant and gives you time to unwind from the stress of the day on the way home. The M3 seems like the perfect daily driver for that.

This will sound way harsher than I mean it to, but if you're more concerned about cost of resale or maintenance on a car then you are about driving it, you shouldn't have it in the first place.

Drive the m3, and get a 2nd set of all season or snow tires to extend the winter use. When you find your 981, ditch the miata and drive that.
On really bad winter days tag team with your wife with the Land Rover.

To me, the opportunity to drive one of my cars is a solution looking for a problem.
