I find it ironic that you bought a M3 ZCP for ride comfort.
Like others mentioned, putting 18s on the vehicle will help. Since you acknowledged the fact that you should have test driven the car before purchasing it, I won't stress that point. Also, don't buy sports cars for ride comfort.
Comfort setting in EDC definitely is less harsh than the normal or sport, but it won't turn the car into a 7-series.
It's really not that bad, but might feel exaggerated since you are coming from a 320. You may get used to it in a couple weeks.
