2015 Mercedes-Benz B-Class 2.1L Diesel · M10 RGP

This Mercedes-Benz B-Class presents a clean and stable MOT history, with the most recent test on 5 June 2025 at 23,584 miles showing no advisories or defects. The trend over the past four annual inspections—each passing without fail—indicates consistent roadworthiness, suggesting the vehicle has been maintained to meet DVSA standards. The absence of recurring advisories or major failures points to either diligent servicing by previous owners or naturally low-wear components. That said, the lack of any recorded advisories also means there’s no historical precedent to gauge how the car might handle higher-mileage issues, such as suspension wear or brake system degradation, which are common in vehicles of this age. The mileage accumulation is unusually low for an 11-year-old vehicle, averaging just over 2,100 miles per year. This suggests either infrequent use, prolonged periods of inactivity, or a combination of both. The gap between the 2022 test (9,286 miles) and the 2025 test (23,584 miles) covers nearly three years with only 14,300 miles logged—a rate that would be typical for a secondary or occasional driver’s car rather than a daily commuter. Such low mileage reduces wear on consumables like tyres and brakes, but it may also mean components like suspension bushes, coil springs, or hydraulic fluid have seen minimal real-world stress. Without advisories, there’s no evidence of neglect, but the buyer should verify whether the car has been stored correctly to avoid issues like seized bearings or degraded seals from prolonged inactivity. Given the clean MOT record, the buyer’s primary focus should be on components not routinely checked during MOTs but critical for long-term reliability. Inspect the suspension for worn or degraded bushes, particularly in the rear, where binding can develop over time despite low mileage. Check for any signs of fluid leaks—power steering, brake fluid, or differential—around the wheel arches and underbody, as stagnant fluid can degrade seals. The brake system, while not flagged, should be tested for uneven wear or binding calipers, especially if the car has sat unused for extended periods. Structural integrity is less of a concern with this mileage, but a thorough check for corrosion in wheel arches, sills, and exhaust mounts is prudent, as moisture retention from infrequent use can accelerate rust. Finally, verify the condition of non-MOT-checked items like the battery, which may have degraded due to intermittent use, and the condition of rubber hoses and belts for signs of cracking. The absence of advisories is a positive sign, but the buyer should treat this as an opportunity to conduct a pre-purchase inspection by a qualified mechanic, given the car’s age and the unusual mileage pattern. This will ensure no latent issues have developed outside the scope of the MOT.
