2012 Mercedes-Benz C 6.2L Petrol · BS12 AMG

The vehicle passed its most recent MOT on 29 July 2026 with no defects or advisories recorded. The overall maintenance trend appears stable, as the two most recent inspections have been clean. However, a review of the historical data reveals a pattern of intermittent issues, particularly regarding the rear drivetrain, which suggests that while the vehicle is currently roadworthy, certain components have required ongoing monitoring over the last several years. The recorded mileage of 17,693 miles is exceptionally low for a fourteen year old vehicle, averaging approximately 1,264 miles per year. While this implies minimal wear on the engine internals and transmission, such a low annual usage rate often indicates long periods of standing. From a mechanical perspective, this is frequently more concerning than high mileage, as static vehicles are susceptible to the perishing of rubber seals, the degradation of lubricants, and the seizure of braking components. A recurring advisory regarding an oil leak from the rear differential and axle was noted in 2020, 2022, and 2024. Although described as not excessive, the persistence of this leak suggests a failing seal or gasket. During a test drive, listen for any whining or humming noises emanating from the rear of the vehicle, which can indicate lubricant starvation or bearing wear. A physical inspection of the rear axle housing is necessary to check for fresh oil residue or staining to confirm whether the leak has been professionally repaired or simply ignored. Given the vehicle's age and infrequent use, several time-based degradation points require scrutiny. Inspect all tyre sidewalls for fine cracking or perishing, as tyres often reach the end of their safe service life due to age regardless of remaining tread depth. Check the brake discs for heavy surface corrosion and ensure the calipers are not binding, which is common in low-mileage cars. Finally, verify the service records to ensure oil and filters have been changed based on a calendar interval rather than mileage, and check the health of the 12V battery and the condition of the suspension bushes to ensure they have not hardened or cracked from disuse.
