So from the article there were 3 made and Holden has 1.... Where are the other 2?
From what I have read, there were four bodies made. Here is an extract from an article that was written in 1994;
Between October 1969 and April 1970, all studies of the GTR-X had been completed, as had the manufacture of four
chassis and bodies. Reinforced Plastics, a specialist company at Clayton, in Melbourne, was responsible for the bodies.
Final assembly of two GTR-X prototypes took place during May 1970. The first went to Holden's proving ground at Lang
Lang for initial shakedown tests to evaluate ride, handling, and braking characteristics. It was later written off in a barrier crash test, where it perfonned as well as was expected.
The second of the completed GTR-X prototypes led a far more celebrated life. It was sent on a round of the country's motor .
shows, ostensibly to "test buyer reaction", as the press handout said at the time. Such a program was most out of character for Holden, which was nonnaIIy very secretive about future model programs. The car also appeared at the Mount Panorama circuit near Bathurst, an hour northwest of Sydney and home of Australia's most famous and prestigious production salooncar
race, where it completed a few demonstration laps in front of thousands of enthusiastic sports-car fans. A few motoring
joumalists were allowed to drive it, and they spoke of 210 kilometers per hour (about 131 mph) and 0-60 runs in 8.5
seconds.
A third prototype, partially assembled before the program was abandoned, was pushed aside in the studio and forgotten until quite recently. A Melboume enthusiast has purchased it and plans to completely rebuild it.
The fourth shell was never used and is believed to be languishing at Lang Lang.
Remember that this was back in 1994.. I will post the whole article in the other GTR-X thread soon.
cheers
