2017 Mercedes-Benz B-Class 2.1L Diesel · KT67 CLU

The 2017 Mercedes-Benz B-Class shows a consistently strong roadworthiness record, with the most recent MOT on 19 December 2025 at 27,449 miles passing without any defects. This reflects a stable maintenance pattern over the past three tests, though the 2023 inspection did identify a minor but notable issue with the nearside front outer tyre cut and a worn wiper blade. No structural or mechanical advisories have appeared since 2022, suggesting the vehicle has been kept in sound condition. The latest test’s clean pass indicates no immediate cause for concern, though the low mileage—just 2,340 miles since the last MOT—means some components may not have been stressed enough to reveal hidden wear. The mileage progression reveals an unusually low annual average of around 3,050 miles, with no significant gaps between tests. The vehicle’s usage appears consistent and light, moving from 13,582 miles in 2021 to 27,449 miles in 2025 without abrupt jumps or prolonged inactivity. This pattern could imply limited high-speed driving or infrequent long-distance use, which may have preserved some wear items longer than expected. However, it also means certain high-mileage components—such as suspension bushes or brake calipers—may not have undergone the usual cycles of stress, potentially masking early deterioration. Given the history, a buyer should prioritise an in-person inspection of the nearside front tyre for further cuts or structural damage, even if the 2023 defect was deemed minor. The suspension system—particularly the rear bushes and coil springs—should be checked for uneven wear or binding, as these are common points of failure in this model. Brake discs and pads, while not flagged in tests, warrant scrutiny for uneven wear or glazing, especially if the vehicle has been used for occasional spirited driving despite the low mileage. Finally, the windscreen wiper blades, last noted as defective in 2023, should be replaced as a preventative measure to avoid obscured visibility in rain. No major structural corrosion or drivetrain advisories appear in the record, but a thorough underbody check remains advisable.
