The HDT Commodore of the 1986-1988 era represents a special time in Australian automotive history. These weren't your average Commodores. They were breathed on by Peter Brock's Holden Dealer Team, transforming them into performance icons. For Kiwi enthusiasts, owning an HDT Commodore is about more than just transport; it's about owning a piece of motorsport heritage. But like any classic, they have their quirks. Here's a Kiwi's guide to keeping yours on the road.
Given their age, HDT Commodores are prone to a few common issues. Rust is a major concern, especially in coastal areas of NZ. Check thoroughly around the wheel arches, sills, and underbody. Engine issues, particularly with older carburetors, are common if not properly maintained. Suspension components also wear with age, leading to handling problems. Parts availability can be challenging, requiring specialist knowledge and potentially importing from Australia.
