2015 Mercedes-Benz B-Class 1.5L Diesel · KM65 COU

The vehicle remains roadworthy, though the maintenance trend indicates a pattern of reactive rather than proactive care regarding consumables. The most recent test in November 2025 at 54,149 miles passed without mechanical failures, yet it highlighted significant advisories across all four tyres for cracking and perishing. This suggests that the rubber is deteriorating due to age rather than tread wear, a common issue with low-mileage vehicles that sit stationary for extended periods. At 54,149 miles, this 11-year-old Mercedes averaged approximately 4,923 miles per year, which is significantly below the UK national average. The mileage accumulation is remarkably consistent, with annual increases of roughly 1,500 to 2,700 miles recorded between 2022 and 2025. While this low usage generally implies less strain on the drivetrain and engine components, the infrequent use increases the risk of dry rot in rubber seals and degradation of fluids, as evidenced by the recent tyre condition. A buyer must prioritize a physical inspection of the windscreen, as it has been a recurring defect since at least 2022 and remains unaddressed across four consecutive tests. The failure in November 2022 for inoperative registration plate lamps and a deep tyre cut confirms that basic exterior items are only replaced when they fail a test. Given the low mileage, the inspector should also check the suspension bushes for signs of cracking and examine the brake discs for corrosion, as these components can seize when a vehicle is not driven frequently.
