James,
The VIN numbers should be very close if that was the case no? If you sort the VIN numbers in the Technical Manual (Car Registry [click on Home>Car Registry under Content] you then can sort the VIN numbers and check it) you might find the VIN numbers to be close. I'm sure yo know how to get there, I'm just showing it in case you need a helping hand
Mine is within 3 numbers of another member here, his car I assume must have been 3 cars behind mine on the final assembly line
I meet him last year at a car show.
