2018 Mercedes-Benz B-Class 1.6L Petrol · RF68 KLS

The vehicle most recently passed its MOT on 19 November 2025, though it did so with an advisory regarding thin front brake pads. This specific advisory is a recurring point of concern, having first appeared in the November 2024 test. While the overall maintenance trend remains stable in terms of passing the legal requirements, the repetition of this advisory suggests a reactive rather than proactive approach to consumable replacement, indicating that the braking system is now due for immediate attention. With a recorded mileage of 44,916 miles over approximately eight years, the vehicle has averaged roughly 5,614 miles per year. This is significantly lower than the national average for a vehicle of this age. While this low usage implies reduced wear on the engine, gearbox, and interior trim, it introduces specific risks associated with low-intensity use and potential periods of standing. Low-mileage vehicles are more susceptible to the degradation of rubber components and the accumulation of moisture in fluids, which can compromise long-term reliability if not managed through a strict calendar-based service regime. Prospective buyers should pay close attention to the braking system and tyre condition. Given the persistent advisory for the front brake pads, a test drive should focus on detecting any brake shudder or high-pitched squealing, and the pads should be visually inspected for remaining thickness. Furthermore, the MOT history reveals a pattern of uneven tyre wear on both the nearside front and nearside rear, including a dangerous failure in 2023 due to exposed cords. This suggests a potential misalignment of the steering or suspension geometry. Inspect the current tyre treads for irregular wear patterns on the inner or outer edges, which would indicate a need for a professional four-wheel alignment. Due to the low annual mileage, it is essential to verify the vehicle's service history to ensure oil and filter changes have been performed based on time intervals rather than mileage alone. Inspect the tyre sidewalls for fine cracking or perishing, which occurs as rubber ages regardless of tread depth. The battery health should be tested, as infrequent short trips can lead to chronic undercharging. Finally, check the brake discs for surface corrosion and ensure the calipers are not binding, as components that sit idle for extended periods are prone to seizing, which can lead to premature wear and reduced fuel efficiency.
