Had a chance to drive shortly(45mins) M3 Coupe with M-DKG(press car with M plates). In short-awsome! Best buy all-over... IMHO all sequential manuals a la F1, e-Gear or R-Tronic will be history in less then two years. YES, M-DKG is that good IMO. Blistering fast in gearchanges, smooth enough at the same time, no stupid need for throttle modulation as on sequential manual... Fantastic... For me new M3 only with M-DKG. I am so impressed that I will order one...
One last thing-M3 with M-DKG is faster then R8 with R-Tronic. In fact belive it or not above 200km/h a lot faster.
