All HJ models, aside from the One Tonner, were easily identified from the HQ by having a squared-off frontal treatment with wraparound indicator lights.

The mainstream passenger car range consisted of 4-door sedan and 5-door wagon models in three trim levels.

[2] The performance-orientated Monaro range included two-door coupe and four-door sedan models: The base model Monaro Coupe was not carried forward from the HQ series, and the new range also saw the demise of the Monaro GTS350 Coupe and Sedan, meaning that the imported Chevrolet 350-cubic-inch (5.7-litre) V8 engine was no longer offered in any Holden model.

[3] Commercial vehicle derivatives included coupe utility, panel van and cab chassis truck models: There were two special vehicle packages available based upon various commercial vehicles: The base utility and panel van models did not carry the Belmont name which had been applied to their HQ series equivalents, and they were marketed simply as the Holden utility and Holden panel van respectively,[4] while The Sandman variants were equipped with various features from the Monaro GTS models.

If a cab chassis or van was optioned as a BO6 (ambulance) it was fitted with the HJ Premier front and door trims.
