I ordered it with edition 1 as it adds a bit of a nice flair to make it more appealing visually, merc assured me the gearbox is more responsive,found using paddles on a e63 frustrating as several hard downshifts with the paddle were completely ignored, found it better to leave it in auto but hopefully all that is remedied.I have no doubt it wont be as sharp as a m3 but it will probably have more theater to it.
