The window sticker on my former black A12 had an 0423 A54, on the bottom block left of the total. It was a 4 26 EAD and about a 5 11 delivery to S.J. Reynolds, Inc., Poughkeepsie, NY. Maybe it had something to do with the actual scheduled start of production so that the dealer could then be able to predict or track the delivery date? I wonder what the A54 means (A58 in the case of the above example)? The repro window stickers don't try to duplicate any of those numbers as far as I know? My A4 has an EAD of 6 3 and the Bill of Sale is dated 6 17, exactly 2 weeks.
