Mine is #185, with a completion date of, um, whenever the Saturday at Carlisle '06 was (sometime in mid May) . I don't remember what date was stamped on the plate, but I think it's 5/06. This tells me that they are not sequential, for whatever reason. 'tis a puzzlement.
Back to the car in the ad, it plainly says 6/24/05 on the plate. I need to get my eyes checked - again.
