I did the tour last year and have no regrets. I am still amazed at how these things go together! You will be required to check your cell phone and any cameras at the door as they are not allowed on the production floor. If you are a BMWCCA member, there is a discount for the tour, $2 U.S. if memory serves me right. Take time for the museum tour as well as it is very informative. Have fun!
