<VV> Production date question: When was my '65 built?

Hi Charles,

The VIN is unique to the production plant, there was no synchronization of VINs.  As far as I know, that's still true.  So, a car with a higher sequence number could easily be produced prior to a car from another plant, if the plants produce cars at different rates, have a stoppage, start later, etc.  All the VIN tells you is when that car came off the line relative to other cars made at the same facility.
