You're right, like BMW's current lineup, Mercedes does not offer anything in between the AMG Appearance Package and a true AMG vehicle. But in the future, just as BMW is expanding the range with M Performance line to fill the gap between MSport and M-proper, so may Mercedes do the same with the AMG lineup. I would not count it out as a possibility, anyway.
