The Holden HDT Commodore stands as a monument to a golden age of Australian motoring. These weren't just ordinary Commodores; they were breathed on by Peter Brock and his Holden Dealer Team, turning a practical family car into a desirable performance machine. These cars represent a significant part of New Zealand's automotive culture, with many finding homes across the ditch.
Rust is a major enemy, especially in coastal areas. Check sills, wheel arches, and around the windscreen. Engine issues can arise from modifications and age. Suspension components will likely need replacement, and the original Bilstein shocks, if fitted, are often tired. Finding original HDT components also becomes a real challenge as time goes on.
WOF tips
WOF inspectors will pay close attention to rust, especially in structural areas. Modified suspension needs to be certifiable. Brake performance will be scrutinized, as will the condition of tyres. Make sure all lights are functioning correctly, as these cars use older wiring systems.

What kind of maintenance schedule should I follow for my HDT Commodore?
Given its age, a more frequent inspection schedule is recommended in addition to the standard 10,000km service interval. Pay close attention to fluid levels, hoses, and belts. Regular oil changes are crucial. Given the age of the vehicle, consider replacing all fluids (coolant, brake fluid, power steering fluid) every two years, regardless of mileage.
Are there any common engine problems specific to the HDT Commodore I should be aware of?
Engine issues can arise due to modifications and the age of the vehicle. Keep an eye out for oil leaks, unusual noises, and overheating. Regular servicing and using quality parts are essential. Check for any signs of wear or damage to the engine components.
What are some common suspension issues with the HDT Commodore, and how can I address them?
Suspension components on the HDT Commodore are likely to need replacement due to age. The original Bilstein shocks, if fitted, are often tired. Look for worn bushes, leaking shocks, and sagging springs. CARFIX stocks replacement shocks and suspension components to help restore the handling of your HDT.
Is the HDT Commodore a good daily driver, or is it better suited as a weekend car?
The HDT Commodore can be a rewarding classic, but it requires diligent maintenance. It's not necessarily ideal as a daily driver unless meticulously maintained. A well-sorted HDT is a joy to drive and a valuable investment, but be prepared for more frequent maintenance than a modern vehicle.
