Start with what the Holden HZ is: a 4-door sedan (car) / sedan / 5-door station wagon / 2-door Ute (vehicle) / ute / 2-door Sedan delivery / panel van / 2-door cab chassis with 3.3 , built from 1977 to 1980, as the oil crises and the first emissions rules rewired the industry. What it meant takes a little longer.
The story
Holden HZ is a full-sized automobile which was manufactured in Australia between October 1977 and April 1980 by Holden in a variety of equipment levels and in several different body styles. It was also assembled in New Zealand.
What is underneath
The engine is 3.3 other versions carried different engines, listed in the specification table below. Drive goes through a Ubl | 3-speed manual | 4-speed manual | 3-speed automatic. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Its place in the line
In the Holden line-up the Holden HZ has a clear place: it replaced the Holden HX; it handed the line to the Holden WB (utility, cab chassis) / Holden VB Commodore; the factory was Acacia Ridge, Dandenong, Elizabeth, Pagewood. The cars a buyer would have weighed it against include the BMW 7 Series, the Ford Fiesta, the Toyota Supra. Nearby in the Holden catalogue sit the Holden 48-215 and the Holden Adventra.
Owning one today
MotorJury scores cars on the United States complaint and recall record, and the Holden HZ has none: too old, too rare, or never sold there. Its value today is a collector's question, decided by provenance and condition rather than by a class average.
