Those debating about M3, I don't use M3, I'm using M5. All I can say is grip is terribly lacking if the road is a little wet at all.

I've skidded my car numerous times
- couldn't see bump from afar then suddenly brake
- others suddenly serve into my lane without signal
- not enough concentration, car in front suddenly slow down

Even at dry, its still not that good, I've skidded ones when I was furious and went very fast and someone suddenly come into my lane.
