My understanding is that they are all "assembled" in Vance, AL, but many components are shipped over from Germany and other European nations, not just AMG engines, but ALL engines, transmissions, tranfer cases, differentials, etc. I believe the bodies are all US made, not sure of the frame. Certainly some of the problems occur at the plant itself, but the Germans are just as much to blame for some of the gripes about the ML's quality, such as oil consumption and leaks and mistrust of the transmission..
