The Mercedes-Benz S-Class W140, produced from 1993 to 1998, epitomizes luxury and engineering brilliance, showcasing Mercedes-Benz's relentless pursuit of perfection. Distinguished by its commanding presence and cutting-edge technology of the era, this generation of the S-Class captures the hearts of enthusiasts in New Zealand. However, due to its intricate design and age, prospective owners must prioritize thorough inspections and ongoing maintenance to ensure its optimal performance.
Common issues with the W140 include complex electrical systems that are prone to failure. Suspension components, such as self-leveling suspension systems, can be very expensive to repair. Rust can develop, particularly around the wheel arches, sills, and door bottoms. The air conditioning system, with its multiple zones and components, is also a common point of failure. Many of the rubber components are reaching the end of their lifespan so must be replaced. Engines are generally reliable, however, the complex water cooling systems are prone to failure.
During a WOF inspection, focus on suspension components, brake performance, and rust. Ensure all lights function correctly. Check for leaks from the suspension and power steering systems. The condition of the tires is also important. Pay close attention to the windscreen condition, as replacements can be expensive.
The W140 S-Class is equipped with a range of powerful engines, from impressive inline-sixes to robust V8s and V12s, offering excellent performance. The interior beckons with spacious luxury and high-quality materials, featuring state-of-the-art technology for its time that still impresses today. The ride quality is exceptionally smooth, making every journey delightful.
As with any sophisticated vehicle, regular servicing is crucial. For example, the cooling system generally requires attention around the 150,000km mark. Key parts such as the water pump, thermostat, and radiator hoses should be inspected to prevent costly breakdowns.
