Just took delivery of a 2005 545I in Munich and everything went very smoothly. I showed up at the Delivery Center about 9:30 on a Monday and had to wait about an hour. This because Mondays and Fridays tend to get the most traffic. Anyway, an hour wait was not unpleasant as BMW gives you a chit for free eats and drinks in their cafeteria plus there were plenty of Bimmer owners around to talk to.
After an hour, one of the delivery specialists came up and introduced himself and reviewed all the paperwork then walked me to the garage and my new car. At this point, he launched into a detailed description of all the features in the car. But, since I'm very familiar with the 545, I told him to skip that part. With that, he wished me a good drive and helped me get the car out of the delivery garage which has an oddly narrow door.
All-in-all, it was a pleasurable experience and the Delivery Center personnel were very professional. Although I speak reasonably good German, the entire staff were all fluent in English
I do recommend that, if your travel plans allow, arrange to pick up your car midweek and thus avoid the Monday-Friday crowd. I shipped my car from Harms in Munich which is about five miles from the Delivery Center but there are a dozen places in Europe you can choose. Since you save considerably on European Delivery (in my case about $5000) it is very much worth considering.
