This is all going to depend on who we have FTAs with, so a car being imported from say Korea comes under an FTA where one coming from say the Hyundai factory in the EU would not & WTA tariff would be added.
Who buys all those Jaguar Land Rover cars? well, the Americans, so WTA with the EU would make no difference anyway.
Nissan & Toyota are another matter, & there’s cars going both ways (to & from the EU), so that just gets complicated.
Cherry picking of the statistics isn’t useful by many of the authors of these articles & studies.
