HZ (1977 to 1980)

The Holden HZ (produced between 1977 and 1980) was the final and most technologically refined iteration of the HQ-style body, famously introducing Radial Tuned Suspension (RTS) which transformed the wallowy handling of previous models into a genuine driver's car. In the 2026 Australian market, the HZ is highly prized for its superior road manners compared to its predecessors; market values for a tidy Kingswood or Kingswood SL typically range from $28,000 to $48,000 AUD, while the luxury Premier variants—often featuring the iconic "Blue" motor updates toward the end of production—command between $45,000 and $78,000 AUD. The performance-oriented HZ GTS sedan (the last of the full-size GTS models) is a significant collector piece, trading between $95,000 and $165,000 AUD, while the legendary HZ Sandman Panel Van remains a cultural powerhouse, with genuine V8 XX7 or XU3 coded examples fetching between $135,000 and $225,000 AUD. Its desirability is cemented by being the last "big" Holden before the downsized Commodore era, attracting a buyer pool of V8 purists, nostalgic surfers, and chassis enthusiasts who value the standard four-wheel disc brakes on GTS and Statesman models. Locally, liquidity is highest for cars in period-correct "Safety" colours like Palais White or Flamenco Red, as 2026 buyers prioritise original RTS-stamped components and factory-fitted bucket seats to distinguish genuine survivors from the many clones in the market.
