Ajay will be seen standing on the edge of a bright pink and a yellow vintage car.
According to a source from the unit, the actor, who has done many stunts in the past, performed the act fearlessly.
In "Golmaal: Fun Unlimited", released in 2006, Ajay made his entry on a sports bike and in the 2008 "Golmaal Returns" he balanced himself on two Hummer cars.
"Golmaal 3" will also feature Kareena Kapoor, Arshad Warsi, Tusshar Kapoor and Shreyas Talpade.
