If you do get a chance to go to Munich, plan on a whole day to visit -- the delivery center is *huge* and will take a bit of time to get through on its own, but the Museum across the street is an all-day affair if you are a real BMW car/bike geek
A lot of folks think the Museum is just the "bowl" building -- because that is what it used to be. The new Museum extends several floors above and down into the ground, and takes up all of the space between the bowl and the 4 cylinders building -- that entire retangular area. A simply amazing collection of vehicles (cars and bikes), including an entire end wall of the Museum being a glass-front showcase for nearly every significant BMW motorcycle ever built -- all suspended in the air. The showcase is the full height of the wall (~4 stories tall, IIRC) -- you have to walk to different floors to see all of the bikes, and they're all about 10 feet from you on the other side of the glass.
Lots of other "stuff" there, too, including a huge (15' x 75'?) touch-interface table with a massive amount of historical info literally at your fingertips in the dark glass tabletop. Ever want to know what the *real* history of the company is? How it was part of George Knorr's railway brake conglomerate after the first war*? How close BMW was to being sold to Diamler and how bike manufacture was saved at the end of the 1950's? All there at your fingertips.
Lots of individual display rooms as well, such as rooms devoted to engine design/examples, body structure,, car racing, bike racing, the Isetta period, etc.
Yeah, I liked the place
* a sidebar: Last time I was in Munich, I was at one of the old factories of the brake company, now known as Knorr Bremse, just up the street from the Museum and delivery center. While I was there, I found out that the building was actually one of BMW's original factories, having been taken over by Knorr when he picked up the remnants of BMW after the war, and then retained when Knorr sold off BMW in the '20s. At one point I felt a bit of a chill when I realized I was standing on a preserved section of rail tracks inside the building where BMW's products first went out into the world -- a birthplace sorta thing. Yeah, corny, but it was cool to me.
