It was excellent. I showed up at the pick up location in Munich and had to wait about 45 minutes which wasn't so bad since they gave us chits for free eats in their cafeteria. Car was exactly as ordered. I did learn that, if your schedule permits, you should arrange for pick up on Tuesday, Wednesday or Thursday as those days are the least crowded.
I dropped the car off at Harms in Munich on 4 October and it showed up at the dealer in Maryland on 30 October again in perfect shape. It's a 545I with NAV, SP, CWP, HUD and folding rear seats and it is unquestionably the best car I have ever owned. I also got satellite radio and am very pleased with how that works. All in all, a fine experience.
