HZ (1977 to 1980)

The Holden HZ (produced between 1977 and 1980) was the final evolution of the full-sized "traditional" Holden body style and is best remembered for the introduction of Radial Tuned Suspension (RTS), which transformed the car’s handling from wallowy to world-class for its era. In the 2026 Australian market, the HZ is a highly coveted classic, with market values for a clean Kingswood SL typically ranging from $35,000 to $60,000 AUD, while the luxury Premier models with factory V8s often command between $70,000 and $105,000 AUD. The sport-focused HZ GTS and the iconic Sandman panel vans or utes have entered the high-end collector tier, with genuine, matching-numbers survivors reaching between $120,000 and $195,000 AUD. Its desirability is fueled by being the last "big" Holden before the downsized Commodore era, appealing to a massive buyer pool of Gen X nostalgia seekers, V8 enthusiasts, and lifestyle collectors who prize the HZ for its superior driving dynamics and classic "tough" stance. Locally, liquidity is highest for cars finished in high-impact period colours like "Flamenco Red" or "Palais White" that retain their original factory-fitted 4.2L or 5.0L V8s, as 2026 buyers increasingly prioritise the refined RTS chassis over the earlier, less-composed HX and HJ models.
