2014 Mercedes-Benz C 2.1L Diesel · KW14 SSX

The vehicle’s most recent MOT test on 2 August 2025—just 11 months ago—confirms it remains roadworthy with no defects recorded at 74,583 miles. While the history is otherwise clean, the single failure in July 2023 for an excessively worn offside front upper suspension arm ball joint suggests a one-off repair rather than a recurring issue. The subsequent test in July 2024 passed without comment, implying the fault was addressed competently. No advisories or repeat failures appear, and the consistent pass rates indicate the vehicle has likely undergone at least basic maintenance between tests. However, the 2023 failure points to a component that, if neglected, could degrade further over time—particularly given the suspension’s exposure to weight and road stress. The recorded mileage of 74,583 miles over 12 years aligns with typical usage patterns for this age, averaging around 6,200 miles annually. There are no abrupt jumps or prolonged gaps that would raise suspicion of either aggressive driving or prolonged neglect. The most notable interval is between the 2022 and 2023 tests, where the vehicle accumulated 6,718 miles in just under a year, yet still passed without issue. This suggests the owner adhered to the 12-month MOT cycle without significant deviations. That said, the lack of service records means wear on non-MOT items—such as timing belts, differential fluid, or brake fluid—cannot be confirmed. Given the history, a buyer should prioritise a thorough inspection of the front suspension components, particularly the offside upper arm ball joint and associated bushes, which were previously flagged. Check for uneven tyre wear, which could indicate alignment drift or worn suspension. The rear suspension should also be examined for consistent wear, as binding brakes or uneven coil spring sagging often develop in tandem with front issues. Corrosion around wheel arches, subframes, and exhaust mounts is another critical area, especially for a vehicle of this age exposed to UK road conditions. Finally, verify the condition of brake discs and pads—while not failed in tests, their lifespan is directly tied to mileage and driving habits. A pre-purchase inspection report would provide clarity on these often-overlooked but critical elements.
