Numbers like that happen when people lie, magazine articles too.

If every option on every 70 Hemi Cuda convertible were known, it would be possible to do that as one example.

Except for the ones with fake fender tags any the made up VIN cars that would taint the data.

If you ask anyone making a claim of 'One of ?? with these options' - Ask them for proof and they will not have any. Chrysler did not track information that way.
