I've already done that (sort of).
My signature has the last numbers of my VIN. It's actually the history of my place in the queue.
I started off
935th in the waiting list. Moved up to
595 after all the fake and dead pre-orders were purged, and ended up with bike
44! If I had a lot more patience, or a lot less cash, I would have waited for the non-R and probably ended up with a much larger number.
