The Pontiac GTO Judge, especially the original 1969 version, was highly desirable for many car enthusiasts with its unique features like Carousel Red paint, rear spoiler, pop-art striping, standard Ram Air 400 engine, and blacked-out grilles.
Blacked-out grilles were not exclusive to the GTO Judge package but were dependent on ordering specific Ram Air engines, as revealed from Pontiac forums and assembly manual details.
The differentiation in grille color based on the engine option was initially viewed as absurd by some enthusiasts, as seen in old discussions on Pontiac forums.
While black grilles were specific to the GTO Judge for 1970-71, for the 1969 model, it was more related to the type of Ram Air engine chosen rather than being exclusive to the Judge package.
