No, sorry you cannot bring a European-spec car across the pond even though we sell similar cars. The engine has not undergone US EPA (environmental protection assholes) testings and it cannot be titled here. You used to be able to import grey market cars but not anymore. Trust me, compared to Belgium a 7 series will be WAY cheaper stateside.
