These are niche cars and do not have huge sales volumes. Point being EU exports far more to UK then the othe way around. Meaning EU needs UK more. United Kingdom has global presence thus the confidence to be a global player rather than be tie down to artificial regional markets. As much as auturky died out in early part of the 20th century with trans-national blocks replacing them [like EU], today the idea of trans-continental trade is coming to the fore as the world shrinks to a global village. Besides I have never understood why if EU is a open market that helps the consumer with lowest proced produce/products why water melons from Spain are koshur but not so from Marocco or Tunisia. Surely open market must mean being able to buy the best/price product from any place in the world. My daughter has a Mini but essentially it is a German built car. Only the brand legacy is British. I have a BMW 4 series, wife a Mercedez A class. Wonder what you own that is from UK?
