Completely agree, Rolf. That's the only way to buy a BMW. If you have an opportunity to do it, its absolutely worth the wait. Welt staff makes a very special event.
I could barely sleep the night before I picked my M3 in Munich last July. Its no secret that you can get a glimpse of your new car at Welt before official delivery time. My delivery was scheduled for 1pm, at 12:59 it still wasnt on the delivery floor. And then it appears... you cant mistake that V8 sound for anything... even in a crowded place like Welt...
What a great experience!
