After 1984, Browne sold the Monza to veteran racer Bryan Thompson, who used it (along with his usual Chevrolet powered, twin turbo Mercedes-Benz 450 SLC) to win the 1985 Australian GT Championship. Thomson competed in the car over the next few years before rebuilding it over the 1988–89 off-season which also saw the Monza body shell replaced with that of a Toyota Supra. He then sold the car in 1990 to an unknown owner who then sold it to longtime Sydney-based sports car racer Des Wall. Wall was also successful with the Supra-bodied car and retained ownership of the car until his death in 2012. The car is owned by his son, racing driver and race team owner David Wall.
