2009 Mercedes-Benz B-Class 2.0L Diesel · NV 2010

The Mercedes-Benz B-Class in question presents a stable roadworthiness record over the past two years, with the most recent MOT on 22 January 2026 at 63,646 miles passing without any defects. This follows a minor anomaly in January 2025 , where the vehicle failed a test on the 27th at 60,593 miles —yet no faults were recorded, suggesting a possible administrative error rather than a mechanical issue. The subsequent retest two days later passed cleanly, indicating no underlying problems requiring correction. The absence of advisories or defects across all five MOTs in this period implies the vehicle has been well maintained in terms of compliance with legal standards, though the lack of recorded issues does not preclude hidden wear from long-term neglect. The mileage accumulation is notably low for a 17-year-old vehicle, averaging just 3,744 miles per year —well below the UK average for its age group. Between January 2023 (53,859 miles) and January 2026 (63,646 miles) , the car covered 9,787 miles in three years , a pace that suggests either infrequent use or prolonged periods of inactivity. Such low mileage can reduce wear on consumables like tyres and brakes, but it may also mask deferred maintenance, particularly in areas less frequently stressed, such as suspension bushes, coil springs, or fluid seals. The absence of mileage spikes or rapid degradation in MOT results further supports the idea that the vehicle has not been subjected to heavy or aggressive driving, though this could also mean some components have not been exercised enough to reveal latent issues. Given the clean MOT history, a prospective buyer should prioritise a thorough inspection of components typically prone to silent degradation in low-mileage vehicles. Pay particular attention to the suspension geometry , including bushings, ball joints, and coil springs, as these can stiffen or degrade over time without significant mileage. The brake system —including calipers, discs, and hydraulic lines—should be checked for binding or corrosion, especially if the vehicle has spent extended periods in damp or salty conditions. While the MOT records show no faults, structural integrity remains a concern; inspect the sill sections, wheel arches, and underbody for signs of corrosion, particularly if the car has been garaged rather than driven regularly. Fluid levels—brake, coolant, and power steering—should also be verified, as stagnation can lead to seal degradation or contamination. The lack of recorded advisories does not eliminate the need for a pre-purchase inspection by a qualified mechanic.
