It doesn't look like that is available for anything other than the MBE900 motor, here is a press release I found on it:
----------------------------------
The Mercedes-Benz Automated Gear Shift (AGS) transmission used electronic controls and hydraulics to manage all gear changes.
The "two-pedal" design is based on the company's 6-speed manual and will be available with the MBE900 in the Business Class M2 early next year in two torque ratings – 520 lbs. ft. and 660 lbs. ft.
----------------------------------
As for the front air suspension, I have yet to here anyone is running it, so I am not sure that that is a disadvantage. I was just looking at the Brocks ad-a-ride site and they finally have a picture of a setup and I swear my FL dealer put mine on wrong. My front has always sat much higher since we added the air ride and I think it is because they have the top bracket flipped the wrong way, I have to check this out this weekend.
