There were only TWO (2) Vettes made for the film. One was shown being built during the production of the film. One of the Vettes was stolen off the Studio Lot prior to release, but was found unharmed within a day.
Its hard to say which Vette was the "Hero" Stingray and which one was built during production. I always thought my Stingray was the "gold" vette in the movie, but I now have a behind the scenes production picture that shows the cut-out hole for lighting the license plate on the rear clip, is identical to my Vette. The shape is unique and the Australian vette does not have the hole in the pictures that I have.
I know that after production of the film, both Vettes were altered somewhat, possibly by Korky. My Vette's interior was died black at one time, and Mid-America restored it back to saddle tan.
If you look at the pictures of the Australian Vette, the hood scoop had been cut out and altered at one time. Not much is known about the ownership of that Vette between the time Korky owned it and the Australian collector bought it.
