Any thoughts on touring the BMW factory and or museum in Munich?
If you're a BMW freak, why not? Museum is a really a fancy show room, but go ahead and get in the drivers of a $75,000 car and you just might get a sales pitch from a pretty girl.
The BMW Welt is free and shows the current collection of BMWs, a few Rolls Royces, and some Minis. The museum is behind it and charges a fee, but is a great way to spend an hour or two. I didn't get to go to the factory because I went on a Sunday, but I believe the museum is closed on Mondays. Pick another day if you'd like to see all 3.
just so you know, you need to make a reservation to tour the factory. A few tours a day are in English.
