So I've had the M4 a few days now and spent a while looking at the various settings available to set it up. All spilt up over comfort, sport, sport plus and effecient.
You can set the engine, suspension, steering, and gear change into anyone of the three modes individually and as a combination of any setting. Lots to play with but I've got it right, 2 buttons on the steering wheel also alow you to switch between two pre set combinations on the fly.
Change of heart on the car I'm really starting to like it, it's brutally fast and equally as thirsty, 17 around the town.
That said I still don't think it's as good as the Z.
