It's surprising that your order went to production so quick, but I guess it's possible you got lucky and picked up a slot after another buyer dropped out with a similar build. What colors/options did you go with?
BTW, good luck with the new F10 M5. I don't know if you recognize my handle but I'm the guy who bought your snow tires when you sold your first E60 M5.
