2012 Mercedes-Benz CLS 3.0L Diesel · RO62 AVW

The latest MOT test conducted on 29 September 2025 resulted in a pass with no defects recorded. Reviewing the history back to 2021, the vehicle demonstrates an exceptionally stable maintenance trend, having passed five consecutive annual inspections without a single failure or advisory. This suggests a high standard of preventative care and a vehicle that has been kept in a roadworthy condition well above the average for its age. With a recorded mileage of 55,714 miles over approximately 14 years, the vehicle has averaged fewer than 4,000 miles per year. While this low usage minimizes mechanical wear on the engine, gearbox, and interior trim, it introduces specific risks associated with prolonged periods of inactivity. Low-mileage vehicles often suffer from stagnation issues that are not always captured in a standard MOT test but can impact long-term reliability. Given the clean MOT record and low usage, the prospective buyer should focus on age-related degradation rather than wear-and-tear. It is critical to inspect the tyre sidewalls for signs of perishing or hairline cracking, as rubber degrades over time regardless of tread depth. Similarly, the brake discs should be examined for heavy surface corrosion or evidence of binding calipers, which can occur when a vehicle stands for extended periods. The health of the 12V battery should be verified, as infrequent short trips or long periods of dormancy can significantly shorten its operational lifespan. Attention must also be paid to calendar-based maintenance. The buyer should verify the service history to ensure that engine oil, coolant, and brake fluid have been replaced according to time intervals rather than just mileage milestones, as these fluids degrade chemically over time. Finally, a physical inspection of the suspension bushes and coil springs is advised to check for rubber perishability or splitting, which can occur due to age and environmental exposure even in the absence of high mileage.
