You can’t get any rarer or more exclusive than one of one.
The HSV GTS-R made its debut at the 2004 Sydney Motor Show, a race-prepared Monaro that was (supposedly) going to be available to members of the public as an Aussie alternative to the likes of a Porsche 911 Cup car.

The GTS-R may have been a concept but it’s a working one and the level of modification over a regular Monaro makes it an extremely special car.
Under the bonnet is a tweaked LS2 good for 335kW/605Nm thanks to forged pistons, billet conrods, hotter camshaft, new exhaust system and recalibrated ECU. There’s also a double-row timing chain and massive aluminium radiator to keep reliability under control.

Inside it’s full motorsport spec, with an FIA-compliant chrome-moly roll cage, onboard fire extinguisher system, dry-break fuel cell and proper AP Racing pedal box with adjustable brake bias.

With HSV reviving the famous badge for its final hero model, its appearance on the market could not have been more perfectly timed.
