Interesting! Sounds like two S-fares would be similar, and both collect a couple of miles!
I know it's off-topic - but I have to ask - otherwise I won't be able to sleep!
So, you are buying the car in Europe and fly over to pick it up and then you ship it off and fly back? Always thought (and last time I checked) Audi, BMW and MB were cheaper when being bought in the US! Am I missing an important point with this promo? Is it open to U.S. Residents only? Couldn't find aything in the rules. And point 9 says something about car pick-up in MUC only - kinda interesting.
