I'm not exactly sure how it was used but a 1969 Camaro RS/SS Z11 convertible was used in some official capacity at a Demolition Derby held at Callister Park Stadium in Vancouver, British Columbia, Canada on Saturday, May 31, 1969.
Two images featuring the Camaro and a trophy queen appeared in the July 1969 issue of a magazine entitled
Motorsport in British Columbia. There is a small, close-up image of the trophy sitting in the passenger seat of the Camaro on the cover of the magazine and a picture of her standing next to the car on page 18. The caption for this image states, "Replica of the Official Indy pace car was provided by Wolfe Chev-Olds. Sharon Parker was trophy queen for the evening of May 31st." The words, "Wolfe Chevrolet Oldsmobile" were affixed to the passenger side quarter panel above the wheel well.
