The early Isuzu Bighorn offers rugged 4WD capability that suited many NZ drivers looking for adventuring cars. These 80's SUVs are well on their way to becoming desirable classics. But what needs to be considered when buying one in NZ?
Rust is prevalent, particularly around the chassis rails, wheel arches, and roof gutters. Diesel engines can suffer from injector pump issues and overheating if not properly maintained. 4WD systems can develop problems with the vacuum actuators or worn-out components in the transfer case. Suspension wear is inevitable after years of use, leading to poor handling and ride quality. Electrical problems can arise due to corroded wiring.
WOF tips
Chassis rust is a major WOF concern. Check the condition of brake lines and hoses for leaks or corrosion. Suspension components, especially ball joints and bushings, must be in good condition. Ensure all lights, including headlights, taillights, and indicator lights, are functioning correctly. Tyre condition and tread depth will be checked. 4WD engagement should be tested to ensure proper functionality.
