The Mercedes-Benz S-Class (W126) from 1985 to 1989 embodies the pinnacle of luxury engineering and timeless design. As a frequent sight on New Zealand roads, this vehicle is celebrated for its unparalleled comfort and build quality. If you’re a prospective buyer in the Kiwi market, understanding what to consider before making this investment is essential as you embrace not just a car, but an emblem of automotive history.
Common problems include rust (especially in coastal areas), failing air conditioning systems (expensive to repair), worn suspension components (especially self-levelling rear suspension), oil leaks from the engine and transmission, and electrical issues. The complicated climate control systems can also be problematic.
Pay close attention to rust around the suspension mounting points and brake lines. Suspension wear is also a common WOF failure point. Headlight alignment and function are always checked, and the complex electrical systems mean all lights and indicators must be working correctly. Modifications from the original design can cause WOF issues.
The W126 S-Class is renowned for its exceptional ride quality and powerful engines, typically featuring a robust 3.0L inline-6 or the graceful V8s. However, age inevitably takes its toll on these magnificent machines. As you explore potential purchases, keep an eye out for common issues. The cooling system tends to require attention around the 150,000 km mark. Essential components such as the water pump, thermostat, and radiator hoses should be inspected to ensure optimal performance. This naturally links to our Cooling category where you can find all necessary parts.
Additionally, suspension components can show wear, particularly the self-levelling rear suspension. Regular maintenance and service intervals are key—stay on top of these to prevent expensive repairs. Annual checks on braking components like brake pads and rotors are crucial; our Braking category offers comprehensive services to keep your vehicle safe. Don't forget about the importance of filtration: replacing air filters and oil filters regularly enhances your vehicle's efficiency and longevity. Our Filtration category has all your needs covered as you ensure your S-Class remains in peak condition.
