I have never found the S2 or the Coupe to be vicious. The lighter weight over the back axle on the S2 means it slides earlier and more gently than the Coupe with the extra bodywork. This is a litytle masked as you can feed the power far more efficiently with the manual box in the S2.
If anything I find the nanny-tronics in the ML63 with 600+bhp far more annoying.
If you come off a cambered roundabout onto a main road in the wet (under power) the camber changes makes the damn thing think it has lost it and it cuts all power. Anyone following close behind suddenly has the sun blotted out and gets to see the supplier details on my number plate.
Accelerator pedals are not binary.
