You've shown your words to be meaningless. You said the U.S. car brands were "completely irrelevant" outside the U.S., here you admit that's wrong. You move the goalpost and change your assertion to something entirely different. But there is no reason to think this statement has any factual basis either. You're just talking out of your &ss.
The only things GM sells in Europe nowadays is the Corvette and the Cadillacs Lyriq, Optiq and Vistiq. Opel and Vauxhall were sold of almost ten years ago.
Ford of Europe is arguably a European car brand which happens to be owned by a US company (in much the same way as Chrysler/Jeep etc are clearly American car brands, despite being owned by a European company).
