my Brabus wheel nightmare
My first clue to that is you mention the proper lug for the wheel is an M12x1.50 ... this lug will NOT fit the M-class in any way. The M-class uses an M14 lug. You also mention that the lugs are tapered, and Brabus wheels (except the Monoblock II, I believe) should not use tapered lugs ("cone seat").
Wheels are generally sized to the lug as well. Wheels made for M14 lugs are usually not recommended for use with M12 lugs, and vice versa. One exception to this is "cone seat" wheels, which can have a large enough hole for 14mm lugs but enough seat area when using a large-head M12 lug. But this is not the case for wheels from AMG, Brabus, Carlsson, etc. as they use "ball seats" which are radiused and the radius differs on the different size lugs.

One of those MBZ quirks that they use bolts instead of studs/nuts. That would make life so much easier...
Good luck!
