2013 Mercedes-Benz B-Class 1.8L Diesel · FY13 SWV

The most recent MOT test on 2026-02-20 confirms the vehicle remains roadworthy with no defects recorded at 127,726 miles, maintaining a consistent pass history across the last three annual tests. The absence of advisories or recurring faults suggests the vehicle has been kept in stable condition, though the February 2024 failure at 103,390 miles—just 43 days before the subsequent pass—indicates a brief but unnecessary delay in testing. No structural or safety-critical components were ever flagged, reinforcing that the vehicle has not experienced progressive mechanical degradation. The most recent test occurred just five months ago, which is well within the acceptable window for a used-car purchase, though a pre-purchase inspection remains advisable. The mileage progression of approximately 9,825 miles per year aligns with typical usage for a vehicle of this age, without abrupt spikes or prolonged periods of inactivity. The gap between the February 2024 failure and the subsequent pass at 103,612 miles (a 222-mile increase) is unusual but not inherently concerning unless paired with other irregularities. There is no evidence of excessive wear or neglect, though the lack of intermediate servicing records means some hidden maintenance—such as fluid changes or suspension servicing—cannot be confirmed. The consistent annual testing pattern suggests at least basic compliance with legal requirements, though it does not guarantee thorough preventive maintenance. Given the clean MOT history, the primary focus of an in-person inspection should centre on suspension integrity, particularly the rear coil springs and bushes, which are common wear items on this model. The absence of advisories does not preclude gradual degradation, so check for uneven tyre wear or excessive play in the steering and suspension. Brake components, including calipers and pads, should be examined for uneven wear or binding, though the lack of past failures suggests they remain functional. Corrosion around wheel arches, sills, and the subframe should be assessed, as this model is prone to rust in high-salt regions. Finally, verify the exhaust system for leaks or excessive rust, as emissions-related failures are rare but possible in older Mercedes-Benz models.
