2011 Mercedes-Benz R-Class 3.0L Diesel · KM60 RMV

The vehicle remains roadworthy, having passed its most recent inspection in July 2025 at 163,919 miles. The maintenance trend appears stable but indicates a pattern of reactive rather than preventative care. While the latest test notes only a minor oil leak that did not meet the failure criteria, the history of defects suggests that components are often only addressed once they reach a point of mechanical failure or legal limit threshold. At 163,919 miles over 15 years, the R-Class averages approximately 11,000 miles per year, which aligns with typical usage for a luxury vehicle of this size. The data shows consistent use, with a 9,000-mile gap between November 2022 and July 2024 tests, and another 5,000 miles between July 2024 and July 2025. This regularity suggests the vehicle has been used regularly rather than sitting for long periods, which is generally beneficial for seals and rubber components in an older Mercedes. A buyer must specifically inspect the front drive assembly, as the record shows severely deteriorated CV boots in both 2020 and 2022. Even if these were replaced, the recurring nature of this fault suggests potential issues with component part quality or premature wear on the joints. The 2024 advisory regarding rear tyres worn on the edge also points toward a potential alignment issue or worn suspension bushes, which should be verified during a test drive to ensure there is no excessive tracking or uneven handling. The oil leak noted in the July 2025 test requires a close look to determine if it originates from a simple cover gasket or a more costly engine seal. Given the age and mileage of the R-Class, a physical inspection should also check for structural corrosion on the underbody and verify the condition of the air suspension system, as these are common failure points for this specific model that are not always captured by standard MOT testing until they become critical.
