What's wrong with this picture?

yeah..... that car had something special. customer/dealer put in a special Order request...
which could be anything within reason, from all of the options available, provided it fits

god knows what, but they did
mind an SOA could also be applied to have something removed... still makes it pretty unique.

Unless of course SOA was applied to all Mexicana's??? but i doubt it, an SOA is unique number linked to a customer order.

that number would be on a form associated with this car only

You'd need to spend some money with valiant infobase in Australia to perhaps get detail on what the special order, added or removed, from standard spec.

laying on your back with your head up under the dash may or may not reveal more, by way of the chalk markings.
