The Mercedes-Benz 123 series, a stalwart of the late 1970s and early 1980s, is celebrated for its durability and engineering excellence. It was a common sight on New Zealand roads back in the day and holds a special place in the hearts of many. But age and mileage means that certain maintenance items are a must to check.
Rust is a major concern, particularly around the jacking points, wheel arches, and along the sills. Diesel models can suffer from injector issues, and both petrol and diesel versions can experience vacuum system leaks causing poor running. Suspension wear is also common, especially in the front end.
WOF tips
WOF inspectors will pay close attention to rust, particularly in structural areas. Suspension components, including ball joints and tie rod ends, are frequent failure points. Brake lines are also susceptible to corrosion and must be in good condition. Headlight alignment is another common issue.
