The Chrysler Sigma, a familiar sight on New Zealand roads in the late 70s and early 80s, represents a blend of Australian muscle and Japanese reliability, thanks to its Mitsubishi roots. These rear-wheel-drive sedans offered dependable transport and a touch of Aussie charm that resonated with Kiwi drivers. Let's dive into what makes the Sigma tick, and what to watch out for if you're considering one today.
Rust is the biggest enemy, particularly in areas prone to moisture. Check the sills, wheel arches, and around the windscreen. Gearbox failures (especially automatics) can occur with age and lack of maintenance. Engine leaks (oil and coolant) are common. Interior trim and electrical components are likely to show wear and tear.
WOF tips
WOF inspectors will scrutinize rust in structural areas. Check for worn suspension components (ball joints, bushes, shocks). Ensure all lights are functioning correctly and that the brakes (discs or drums) are in good order. Steering play can be a concern, so pay attention to its condition. Exhaust systems often suffer corrosion, leading to WOF failures.
