2018 Mercedes-Benz M8 2.1L Diesel · SF18 NZR

The vehicle is currently roadworthy, but the maintenance history indicates a worsening trend regarding front-end geometry. The most recent test in May 2026 at 322,114 miles identified advisories for worn suspension arm bushes on both the nearside and offside front. While these did not result in a failure, they represent a progression from the more severe mechanical failures seen in the previous year, suggesting the front suspension assembly is reaching the end of its service life. The mileage profile is exceptionally high for an eight-year-old vehicle, averaging over 40,000 miles per year. A significant surge in usage occurred between May 2024 and May 2026, where the car covered 97,134 miles in just twenty months. This rapid rate of accumulation puts immense stress on the drivetrain, steering components, and suspension bushings. The transition from a clean record in 2023 and 2024 to multiple failures in 2025 highlights that the vehicle is now struggling to keep pace with high-intensity motorway operation. A buyer must prioritize the steering rack and front suspension during a physical inspection. The 2025 failure for an insecure Macpherson strut and play in the steering rack inner joints indicates a past structural instability that was only partially rectified thereafter. Given the current advisories for worn bushes, an inspector should check for excessive play in the steering wheel and uneven tyre wear which would confirm imminent component failure. The high mileage also necessitates a thorough check of the cooling system and turbocharger, as engine components at this interval likely face significant fatigue.
