The Mercedes-Benz S-Class 500 SE and SEL from 1987 to 1991 epitomize the pinnacle of luxury and engineering from their era. With European sophistication woven into their DNA, these vehicles are a hallmark of enduring quality. Many have found their way into the hearts of New Zealand drivers, offering a taste of opulence. Yet, as with any classic car, maintaining its magnificence requires attention and care.
Common issues to watch out for include: Rust (especially around the wheel arches, sills, and jacking points), failing central locking systems, worn suspension components (especially self-levelling systems), and electrical problems related to aging wiring and relays. Engine issues can arise from neglected maintenance, particularly oil leaks and cooling system problems. Air conditioning systems are often in need of repair.
Specifically for your WOF, pay close attention to: Suspension components (ball joints, bushings, shock absorbers), brake lines (corrosion), rust in structural areas, headlight alignment, and the overall condition of tires. The self-levelling suspension, if fitted, must be functioning correctly. Any significant oil leaks will also result in a WOF failure.
Owning a timeless S-Class 500 SE or SEL in New Zealand is not just about driving; it's about experiencing a piece of automotive history. Though these vehicles were engineered for durability, they do come with their quirks. Regular maintenance is essential to keep them running smoothly. Pay attention to the suspension, as worn components, particularly the self-levelling systems, may require replacement to maintain the ride quality. Additionally, the air conditioning systems often need servicing, especially as they age. Ensure you adhere to service intervals to prolong the life of your vehicle. For example, the braking system is critical—consider a front brake service every 30,000 km to keep your vehicle safe on the road, especially since brake pads and rotors are commonly replaced parts. The cooling system also requires careful monitoring, especially around the 150,000 km mark. Essential components like the water pump, thermostat, and radiator hoses should be inspected regularly.
