The Marzal appeared in action at a public event for the first time at the 1967 Monaco Grand Prix when Prince Rainier III, accompanied by his wife, Princess Grace, drove the car on his traditional parade lap before the start of the race. The car made a second public appearance at the 1996 Concorso Italiano in Monterey, California in honor of Carrozzeria Bertone. The Lamborghini Athon was also exhibited at this time. The car was driven by Prince Albert II during the opening ceremony of the 2018 Historic Grand Prix of Monaco.
