If you a BMW afectionado then it definitely worth a stop, the museum [4.0 hours @ EURO 12.00] [10:00 AM to 6:00 PM - Closed Mondays] covers almost everything they have ever released and a few things that never got to the showrooms as well as a nice selection of non-street cars and motorcycles. in addition there is a tour of the factory available [2.5 hours @ Euro 8.00] but you must call [+49(0)1802 118822] for a Reservation on a tour, you can't just walk in.
