The Mercedes-Benz 123 series is an icon of reliability and engineering, hugely popular in New Zealand. From 1976 to 1981, these cars were known for their robust construction and longevity. However, age takes its toll, making diligent inspection and maintenance crucial for NZ owners.
Common issues include rust (especially around wheel arches, sills, and floors), worn suspension components (subframe mounts, control arm bushes), diesel injector and pump problems (diesel models), and electrical faults due to brittle wiring and corroded connections. Vacuum system leaks (affecting central locking and climate control) are also frequent.
WOF tips
Rust is a key WOF failure point, particularly around structural areas. Suspension components (shocks, springs, bushes) must be in good condition. Check brake lines and hoses for corrosion and leaks. Headlights and taillights should be fully functional. Steering systems need to be free from excessive play. Functionality of seatbelts are mandatory.
About the Mercedes-Benz 123 280 E
The W123 series was renowned for its durable engines, both petrol and diesel. However, diesel models, while long-lasting, can suffer from injector issues and pump wear with age. Suspension components, particularly the rear subframe mounts, are prone to deterioration. Rust is a major concern, especially in coastal regions. Electrical systems, while robust for their time, can develop faults due to age and corroded connections.
Questions owners ask
