It is crazy, but the math still works out because the diplomatic price discount (at least for a US-spec) is about 2x the savings of adding back in the service package (at least the one I got). Almost by accident I found that picking up the car in Munich, vs. ordering through US dealer, we got a discount off the M3 price, which ordinarily is not available. The other good thing is I did ship over a small stash of Castrol 10W60 for top ups, which are not covered by the svc package.
If we end up getting back to the States before the factory warranty period expires, we pick up the remainder of the warranty and maintenance that remains (up to 50K miles).
That's great that you get 10years, 100,000km...is your's US-spec or European?
