The VIN was a 13 digit code. Like 69_SIX_PACK stated you could have a RM21 NOG 123456 car and also a RM21 NOE 123456 car built, while the last six digits are the same the entire VIN is different.
The newer VIN law states that a VIN (now 15 digits) if I remember correctly can not be duplicated for 20 years.
Amazing how an unchallenged lie can become the absolute truth.
