<VV> 1966 vin question

[Mark Plucenik]

This is my first time posting a question so I'm hoping this works.  My car
is a 1966 Corsa convertible. The last digit's of my vin are W120102.
Looking at the Corvair junkyard Primer booklet the last 6 digit's of those
number less 100000 give me the production number for that plant for 1966.
According to this my car is the 20102th Corsa convertible produced in 1966.
But, looking at the total 1966 Corsa convertible production numbers there
were only 3142 ever made. Am I looking at this wrong?  Are the last 6
numbers the total Corvair production , all models.  I'm wondering if the car
is actually a very early 66 production car or a late 66 car?

 

 
Thanks , Mark Plucenik
