2017 Mercedes-Benz B-Class 1.5L Diesel · YT67 RFZ

The most recent MOT test on September 18, 2025, confirms this 2017 Mercedes-Benz B-Class remains roadworthy with no defects recorded at 25,868 miles. The consistent pass history across five annual tests—spanning September 2022 to September 2025—indicates no recurring mechanical failures or advisories that would suggest worsening conditions in suspension, braking, or structural integrity. The absence of failings or advisories in the latest cycle implies the vehicle has been maintained at a basic level, though this does not preclude hidden wear beyond MOT scope, such as internal suspension deterioration or corrosion in less accessible areas. The recorded mileage of 25,868 miles over nine years—approximately 2,874 miles annually—is unusually low for a vehicle of this age, suggesting either minimal use or prolonged periods of storage. The gap between tests is consistent at around 12 months, with no evidence of accelerated wear from rapid mileage accumulation. The near-identical mileage readings for the 2024 tests (22,020 and 22,021) may indicate a temporary hold or oversight rather than a pattern of neglect, but it warrants confirmation that the vehicle was not stationary during this period. Given the clean MOT history, the primary focus for an in-person inspection should centre on components not routinely tested, such as the condition of suspension bushes and coil springs for wear or perishing, as well as the integrity of brake calipers and discs for binding or excessive corrosion. The low mileage also raises questions about fluid levels—brakes, power steering, and coolant—since prolonged inactivity can lead to degradation or contamination. Structural elements, particularly around wheel arches and underbody, should be scrutinised for corrosion, especially if the vehicle has spent time in wet or salted environments. The absence of advisories does not rule out minor issues like worn wiper blades or faded interior materials, but these are consumable and unlikely to impact roadworthiness.
