A) most cars manufactured by European and Japanese brands are built in Mexico and direct imported via NAFTA/USMCA. The fact that Toyota and Honda choose to continue to do manufacturing in the United States is probably seen as a boon to those local communities.
B) the "low quality" image of American brands is pretty limited to the United States, like a lot of American products (California wine, for instance, is generally bottom shelf in the US but well regarded internationally). In Russia, Ford used to be their top marquee. Ford and GM are both huge in Oceania. In LATAM, they're seen as a step up from Japanese and Chinese brands and Volkswagen. In Europe, they're not generally perceived as low-quality; instead, the perception is that they're too large and fuel inefficient for most European roads/cities.
