There are a few different figures around on Holden build numbers. Drive and News seem to agree on the HQ as the biggest selling Holden and the VT as the biggest selling Commodore.
Drive said:
“485,650: The biggest selling Holden of all time, the HQ Kingswood, made from 1971 to 1974.
303,895: The biggest selling Commodore of all time, the VT series, made from 1997 to 2000.

News said: “The VT was the biggest selling Commodore model of all time, with a staggering 303,895 built over almost three years. However, that’s still not as high as the HQ Kingswood (485,650) in the 1970s.”

Carsguide offered this opinion as to why the VT was so successful: “ It also helped that the Falcon of the day was regarded as ugly, prompting buyers to flock to the Commodore in droves.”
