2014 Mercedes-Benz B-Class 1.5L Diesel · B7 NDK

The most recent MOT test on 22 September 2025 resulted in a pass, following a failure on the same day which suggests a minor defect was rectified immediately. The overall maintenance trend for this vehicle is exceptionally stable, with a clean record spanning back to 2022. The absence of recorded defects or advisories across multiple years indicates a vehicle that has been consistently maintained to a high standard of roadworthiness. With a recorded mileage of 49,748 miles over a twelve year period, this vehicle has averaged approximately 4,146 miles per year. This is considered very low usage for a car of this age. While this typically results in reduced wear on the engine internals, gearbox, and drivetrain, such low annual mileage often indicates periods of prolonged standing or a history of short-distance urban trips, both of which can introduce specific mechanical vulnerabilities. Given the clean MOT history and low usage, the buyer should focus on age-related degradation rather than typical wear and tear. It is essential to inspect the tyre sidewalls for signs of perishing or hairline cracking, as rubber compounds degrade over time regardless of tread depth. The braking system should be scrutinized for surface corrosion on the discs and the potential for binding calipers, which can occur when a vehicle is left stationary for extended periods. A thorough check of the 12V battery health is also recommended, as low-use vehicles are prone to premature battery failure. Finally, the buyer must verify the service history to ensure that fluids have been changed based on time intervals rather than mileage alone. Engine oil, brake fluid, and coolant degrade chemically over time, and a lack of calendar-based servicing can lead to internal corrosion or sludge buildup. During a test drive, listen for any stiffness in the steering or clunks from the suspension, as rubber bushes and coil springs can perish or lose elasticity when not regularly exercised. Ensure all service book stamps align with the low mileage to confirm the vehicle history is genuine.
