The marauder vehicle from “Mad Max 2: The Road Warrior”, often referred to as “Red Monaro” is a heavily modified 1971 Holden Monaro HQ Coupe, modified with grille borrowed from a 1940’s Buick. This car is rarely seen up until the final chase. One deleted scene reveals the owners of this car as they stand up wielding weapons. Surprisingly, the driver’s weapon is a machete.
In the final chase scene of “Mad Max 2: The Road Warrior”, the crossbow wielding passenger of this car jumps out onto the Humungus’ vehicle and frees Wez from his chains with a bolt cutter. That same passenger later jumps onto the tanker with a different weapon altogether and attempts to shoot Max from the roof. He is shot and falls off the truck.
Not long after the car is heavily damaged after Max decides to turn around the rig. The Red Monaro is almost crushed under the wheels of the tanker and loses the passenger door. It still attacks nontheless which results in a bent front right wheel.
After Max’s head-on collision with Humungus , this car is not seen driving away along with other marauders , but it’s safe to assume it came out of the chase relatively functional.
