The Mercedes-Benz W123, produced from 1977 to 1985, is a true icon of German engineering and a familiar sight on New Zealand roads. Revered for its durability and build quality, the W123 was available in sedan, coupe, and wagon (estate) configurations, catering to a wide range of needs. These cars are known for their tank-like construction and their longevity, even in the challenging Kiwi climate.
Given their age, common problems in New Zealand include rust (especially in coastal areas), wear in the suspension components, and potential issues with the fuel system (particularly in older carburetted models). Diesel models can suffer from injector issues and wear in the injection pump. Interior trim can also show its age, with cracked dashboards being a common sight.
WOF tips
When preparing a W123 for a WOF, pay careful attention to rust, especially in the sills, floor pans, and around the suspension mounting points. Check the brake lines for corrosion and ensure the brake pads and rotors are in good condition. The suspension should be thoroughly inspected for worn bushings and ball joints. Headlight alignment is crucial, and all lights should be functioning correctly.
