Porsche factory and museum by phil_uk_net
Home of the world's finest sports cars! Factory tours are available but must be pre-booked. Porsche Club of Great Britain arrange these from the UK and it is also possible to arrange yourself by calling +49 - 711/911-5384. The museum is open 9-4 Monday to Friday and 9-5 weekends and holidays.
