I think the combination of letters on AMG are not from a single font, there is an EPS (Encapsulated PostScript) version of it here
It looks to be a combination of a few different fonts (possibly Monolith or FlatIron). MB's own corporate typeface for stationery is Corporate S (and A)
Not sure if this helps or if someone else has a better feel for typefaces
Thanks for that its pretty close but you cant download it and request on the similar topic the font if downloadable for the series range e.g. C230 KOMPRESSOR
