The Mercedes-Benz M-Class (W163) broke new ground as the first luxury SUV to be offered by the famed German manufacturer. Launched in 1997 and available in New Zealand from 1998 to 2002, this model not only showcased the brand's engineering prowess but also promised on-road comfort and off-road capability. While it presents a budget-friendly entry point into the luxury Mercedes world, prospective buyers should approach with care. Let’s explore everything you need to know to keep this iconic vehicle thriving on New Zealand’s diverse roads.
Rust (especially around wheel arches and underbody), failing electrics (window regulators, central locking), oil leaks (engine and transmission), worn suspension components (especially air suspension if equipped), catalytic converter failure.
Check for rust around structural areas, suspension components (especially ball joints and bushings), brake condition (discs and pads), lighting functionality (headlights, taillights, indicators), tyre condition and tread depth. Also, ensure all safety systems are functioning correctly, like ABS, if equipped.
The W163 M-Class ML 320 is not just a vehicle; it's a luxury experience on four wheels, offering a variety of engines from inline-4s to robust V8s, all tailored for exceptional reliability if maintained properly. Inside, you're greeted with an upscale leather interior, even in base models, making every trip a pleasure. However, like any vehicle of its age, regular maintenance is paramount. It's wise to check for common issues such as failing electrics or rust, especially around the wheel arches. Repairing worn-out suspension components—particularly on the air suspension equipped models—can also be costly, so leave no stone unturned when inspecting.
Service intervals around 150,000km bring attention to the cooling system, where parts like the water pump, thermostat, and radiator are due for inspection. This is a great opportunity to check out our Cooling service pack for parts. Routine brake servicing is also crucial, especially for the front and rear, ensuring safety and performance are top-notch. Don’t forget our Brake service packs that cover pads, rotors, and essential parts. Furthermore, keep an eye on the filtration systems, replacing air and oil filters to maintain engine performance.
