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.
