The Final Chapter of the Classic Holden Line
The HZ Holden was the last of Holden’s traditional full-size sedans, wagons, utilities, and panel vans, offering refinement, comfort, and V8 performance in Monaro and GTS variants. By 1980, Holden released the WB Holden, the final iteration of the classic Holden platform before the full transition to modern designs in the Commodore.
The WB Holden represented a subtle evolution, offering cosmetic updates, minor mechanical improvements, and enhanced comfort while retaining the full-size proportions, versatility, and V8 performance that had defined Holden for decades.
