A U.S mile is the same as a U.K mile (imperial mile) which is 1.6 km. What I think the problem might be is the gas / catalyst converter. I don't think the gas in Europe is the same as in the U.S, in fact I am pretty sure of it... I took delevery of a BMW at the Munich Factory years ago for import in the U.S and the catalys converter was changed upon arrival to meet the U.S standard. The car might have to be reprgramed as well, to match the U.K petrol.
