Certainly Frank did a lot of races in open wheelers and sports cars but his "tin top" wins included 3 British Touring car championships (Falcon Sprint, Escort and Camaro), a second at Bathurst, The Australian Sports Sedan championship at a time when it was at least the equal in importance with the Touring cars, He also set up and drove for the BMW team in Australia, sorted and prepared the Tony Longhurst Bathurst Sierra.
About the only thing he did wrong was getting Paul Morris started in racing
Edit: The Sports Sedan was a Chev Corvair which was probably what you saw at the farm Blue, although he may have run a Camaro at some stage.
