What alternative universe are you living in? I have lived and worked in the Middle East, where money is not an issue, and governments tend to use Mercedes and BMW by choice.
South America, having no industry of its own usually makes German cars under license.
The uk manufactures Toyota, Honda and Nissan for RHD and LHD markets world wide. The more prestigious Marques like Rolls Royce, Bentley, Jensen, Jaguar are manufactured in uk for home and global markets.
You are the one making a fool of yourself. American production cars are shit, just like your fantasy knowledge about motor sport. You knowledge is limited to redneck racing ovals, which has never caught on anywhere else. There is a very good reason for that.
