Typically you don't start paying for the Euro Delivery until you get it as they give you a few months before your first payment, but there could be a little overlap, otherwise, you just take your trade in when you pick up your Euro Delivery stateside (worst case you may end up with 1 payment before you get the car back in the US if it is a bit slow getting to you).

All I can say is do it - was a great experience, either saves you a little money or gives you a free vacation with the savings. Munich is awesome with Welt and the factory tour/museum. So much to see close by and the driving is great in the area. It is worth the trip even if you just make it a long weekend!
