He doesn’t know how cars are made and it shows.
When I made Cadillac parts here in Michigan they were shipped to Livonia where they were used to assemble Cadillacs along with major parts from Canada and Mexico. Minor parts like electronics came from a half dozen other nations.
Its true of pretty much all cars. My factory made parts for Ford, Toyota, Chrysler etc and shipped them all over the world.
My Ford Focus, built about two miles away from the plant where I work (supplying parts to Ford) has 40% Canadian and Mexican content (including a German transmission that is smooth as a glove). God Bless America.
