VIN Number #5S08F100009

Fifteen Mustang pilot units with S-code VINs were built at the Allen Park Pilot Plant in 1963 prior to the first assembly of production Mustangs which began in early 1964.

The Mustang III was the ninth pre-production Mustang ever built. The first eight S-code Mustangs have been destroyed or their existence are unknown. It is the only known existing Mustang  with an S-code VIN and according to Mustang historian Bob Fria, it is likely “the oldest known Mustang on the road today.”
