Having a hardtop makes the car basically a coupe so you don't have to worry about your softtop getting damaged.
Winter tires make a big difference plus the car has an LSD so most probably you'll only be stuck if u go out in 20cm+ snow, and don't forget that the M3 is equipped with a very advanced stability system to keep the power under control, unless of course its off then you'll have the time of your life driving to and back from work
At the end , its all about the driver, RWD or FWD or 4WD only makes the difference when you are on the gas, but to brake and turn, its all the same
