On mine, under the right front seat, stamped into the angle iron rail at the front of the seat edge is "M3W 458" indicating the 458th built. Those three digits also are the last 3 of the VIN.
What do you have stamped in that area? What are the last 4 digits of your VIN?
Also, in the wooden surround of the rear boot area, there is likely a body number stamped. Mine is #498, an interesting mismatch. Studying the Register post just adds to the confusion as the numbers get rather wonky with some of the newer machines.
It might be helpful if the Register post had clear instructions on where to find relevant numbers and which ones to add to the post.
Edit: those directions were there in earlier posts, but look to have been omitted on the most recent. I've just added them back in.
