2017 Mercedes-Benz C 2.1L Diesel · AP 7007

The most recent MOT test on 2026-08-06 resulted in a passing outcome, marking a return to compliance after a failure observed just a week earlier. However, the vehicle’s MOT history reveals a concerning pattern of recurring tyre defects, with the 2026 failure highlighting both a deep cut exceeding ply or cord integrity and a structural bulge indicative of severe tyre separation—a failure mode that can compromise road safety and lead to sudden blowouts. The previous MOTs from 2023 and 2024 were clean, suggesting that the tyre issues may have emerged during a period of higher or less consistent usage, potentially exacerbated by prolonged standing or improper storage conditions. This inconsistency demands careful scrutiny, as tyre degradation can accelerate under stress, particularly if the vehicle has been stationary for extended periods without proper protection from UV exposure or physical damage. The recorded mileage of 13,656 miles for a 2017 model year represents a notably low annual usage rate of approximately 1,517 miles per year, which is unusually low for a vehicle of this age and class. Such low mileage often correlates with either infrequent operation or prolonged periods of inactivity, both of which can accelerate wear on certain components. For instance, standing vehicles are prone to brake disc corrosion and caliper binding due to moisture ingress, while suspension components like coil springs and bushes may degrade faster from lack of movement. Additionally, fluids such as brake fluid, coolant, and transmission oil can degrade over time through oxidation and separation, even without significant mileage. The low usage profile also raises questions about whether the vehicle has been adequately maintained during extended periods of non-use, as certain services—like fluid top-ups or tyre rotation—may have been overlooked. Given the history of tyre failures and the low annual mileage, the prospective buyer should conduct a thorough physical inspection of the tyres, focusing on the tread depth, sidewall integrity, and signs of dry rot or cracking. The offside front tyre from the 2026 failure must be replaced immediately, as the structural bulge and ply exposure are critical safety concerns. During a test drive, listen for unusual tyre noise, such as a sudden increase in vibration or a loud hissing sound, which could indicate a blowout or internal tyre failure. Additionally, check for uneven tyre wear patterns, which may suggest misalignment or suspension issues that could have contributed to the tyre damage. Beyond the tyres, the buyer should inspect the vehicle’s suspension for signs of wear, particularly the coil springs, shock absorbers, and suspension bushes, which may have deteriorated from prolonged inactivity. Pay attention to any clunking noises from the front or rear suspension during cornering or over bumps, as this could indicate worn bushings or broken spring mounts. The brakes should be examined for corrosion on the discs, particularly on the offside front side where moisture may have accumulated, and for signs of binding or excessive heat discolouration. Test the braking system by applying firm pressure to the pedal, ensuring there is no sponginess or excessive pedal travel, which could signal fluid degradation or worn brake pads. Finally, given the low mileage and potential standing periods, the battery should be checked for signs of corrosion or poor connections, and the vehicle’s fluid levels—including coolant, brake fluid, and transmission oil—should be topped up if necessary, with a reminder to replace fluids that have been in the system for over five years, as they may have degraded significantly. If the vehicle has been stored outdoors, ensure the doors and windows are closed to prevent further tyre or structural damage.
