Purchased from the first promo. this seat is number KM 14 which is the 4th seat released to the public. The 1st ten numbers were reserved for the Miles COBRA project.
Since the seats are now $695, this one is a bargain if it fits the person ordering it.
It's the first one I've seen on Ebay.
Good Luck
