Cars
 

GM Production records and what GM Produced as prototypes or 1 off’s are different

There are:

- mules
- prototypes
- pilots
- production vehicles
- dealer conversions

GM production records unambiguously list two (2) 1969 ZL1 Corvettes ... a number which includes cars from only the pilots & production categories, nothing more.

The "total number rumored to be in existence" includes cars from all of the above categories.
