Mainly aimed at Fox as I know he's done this but there may be others too; in May I'm planning a roadtrip with some friends and one of the stop-offs is Munich for the BMW Factory Tours. We we're planning on doing the "Premium Tour" which is all 3 attractions (Museam, Group Plant and Welt), any advice from those who have been before?
I did Museum and Welt - Welt is free of charge, so we just paid for the Museum. It was really interesting though I was sad about the lack of E39's and vowed never to buy another BMW product again in protest.
The best bit for me was BMW Rent - I took an F10 M5 around the Autobahn for 70 euro. Awesome!
