Hmm… and Volvo is owned by Ford, who sold of, what? Freightliner (some big-rig company) or something a few years back.
Ford bought only the automobile division (Volvo Cars) from Volvo. The truck manufacturer Volvo, which also owns Mack, is not related to Ford.
Those brands aren’t used in all countries. IIRC none of the 3 high-end brand names are used in Japan.
