I bought my CMC classic Speedster body 11/1/1988. The invoice number (same as gold id plate) is S-2244 so would assume yours is earlier (wow! almost 1000 earlier). That # is also on my Certificate of Origin. I would think the State of Arizona could provide info on when that VIN was assigned.
I tried to research one from Michigan for a CMC Speedster that was now in the UK. First, Michigan DMV said I needed to send $10 for cost of research. I sent the $10 and they said their records didn't go back that far! DMV is a bureaucratic zoo - regardless of state. In Fl, it isn't even called DMV - it's the Office of Taxation (so at least you know what to expect).
