The phrase references the desire to acquire vehicles featured in the 2015 film Mad Max: Fury Road. These are not standard consumer automobiles but rather heavily modified, post-apocalyptic machines constructed for the movie. An example would be a replica of the War Rig or one of the pursuing vehicles used by Immortan Joe’s forces.
The interest stems from the vehicles’ unique aesthetic and the cultural impact of the film. The film’s design aesthetic revitalized the post-apocalyptic genre and the vehicles became iconic symbols. Historically, film vehicles often generate significant interest, with collectors seeking original props or building replicas.
