BMW (and so do Porsche, Mercedes, VW: in Scandinavia also VOLVO, in France I know Peugeot has, Renault probably too) have a special export divisons for European pick-ups of car going 'overseas'.

They will guarantee you that the technical specifications meet the standards of your country - they too can/will arrange proper car-papers, the (european) duty-free-allowance, insurance and plate (#) and shipping (they offer also a tour of the manufacturing facilities).
