Following on from the success of the HQ and with an influx of European models entering the market, Australians were presented with a wider range of choices. The Monaro received a heavy face lift to satisfy a more demanding buyer. Introduced in October 1974, the HJ Monaro GTS, with its new facelift, optional front and rear spoilers, offered extra comfort, a comprehensive sports instrument panel of its own and greater emphasis on body detailing to further distinguish it from other models. Beefier HJ styling was matched by extra-strength bumpers. The HJ Monaro upgrade was more imposing than its predecessor and the GTS featured a prominent, blacked-out grille, bigger wrap-around rear lights, more aggressive side vents and decals. Full foam high-backed seats came in a variety of trims and colours. The GTS instrument panel featured multiple ventilation outlets and clear recessed instruments with international symbols. The first factory front and rear spoiler options gave the HJ GTS real presence, the deep rear spoiler and new tail lights in particular bolstering its sloping boot line. As the imported Chevrolet 350 was de-tuned to meet US anti-pollution legislation, it no longer made sense as a premium performance option. Instead, Holden boosted the compression ratio of the local 308 to close the performance gap. The HJ has proved to be a popular favourite amongst the Holden Monaro range.
