Holden HQ 1971-1974

The Holden HQ series is a range of automobiles that was produced by Holden in Australia from 1971 to 1974. The HQ was released on 15 July 1971, replacing the Holden HG series. It was the first ground-up redesign of the Holden line since its original release in 1948,  and included an all-new body, chassis, and suspension. The HQ was later developed into a series of successor models, finally ending production when the WB series was discontinued in 1984.
