Dean says the buyer had verified the VIN (serial number) of the car, but they had to verify the engine number to make sure it had belonged to James Dean. The VIN, which is permanently attached to the car would identify the car, but the engine could have been changed, so the engine number is not a reliable indicator. Additionally, unlike the VIN, engine numbers are not recorded by states, so Sam would not have been able to use it to find the original owner as was shown. See more
