2014 Mercedes-Benz C300 Amgline Prem+btec Hybrid 2.1L Diesel · ML64 EUB

The vehicle most recently passed its MOT on 1 December 2025 with no defects recorded. When reviewing the broader history, the maintenance trend appears to be improving, moving from a series of advisories regarding braking components and tyres in 2022 and 2023 to a clean bill of health in the latest inspection. However, the failure in December 2024 due to insufficient service brake efficiency indicates a period of neglect or a sudden failure of the braking system that required immediate rectification. The recorded mileage of 237,525 miles is exceptionally high for a twelve year old vehicle, averaging nearly 20,000 miles per annum. While consistent high-mileage usage often suggests the car has spent much of its life on motorways, which can be less taxing on the engine than urban stop-start driving, the sheer volume of distance covered places significant stress on all mechanical assemblies. Prospective buyers should anticipate accelerated wear on the drivetrain, suspension bushings, and the hybrid system components. Particular attention must be paid to the braking system given the recurring history of worn pads, pitted and scored discs, and the previous major failure in braking efficiency. During a test drive, the buyer should be alert for any brake shudder through the pedal or steering wheel, which indicates warped discs, and any uneven stopping performance. It is essential to verify that the braking system has been fully overhauled rather than just patched to pass the MOT, as the history suggests a pattern of allowing consumables to wear beyond optimal limits. The previous advisory regarding a front oil leak requires a thorough physical inspection of the engine bay for evidence of seepage or residue around the gaskets and seals. Listen for any abnormal engine knocks or suspension clunks over uneven surfaces, as the high mileage likely means the coil springs and suspension bushes are nearing the end of their service life. Finally, given the hybrid nature and extreme mileage, the buyer must scrutinize the service records for evidence of transmission fluid changes and verify the health of the 12V auxiliary battery to ensure the vehicle starts and operates reliably.
