Im also stationed in Germany and i have been looking at changing my bmw over but when i emailed importers they told me the car was not worth converting. It would cost 3500 just for the epa test alone plus it needs a catalyic converter which runs around 2500 so i was looking at between 8000 and 10000 to convert a 1993 5 series.if you still want to look into it hear are some importers email adresses they are in maryland and coneticut.
