2019 Mercedes-Benz B-Class 2.1L Diesel · FM68 ORN

The 2019 Mercedes-Benz B-Class presents a stable and improving maintenance trend, culminating in a completely clean pass at its most recent examination on 15 January 2026 at 67,046 miles. Since a failed test on 16 January 2023 at 36,885 miles—which required a same-day retest—the vehicle has passed three consecutive annual inspections without a single defect or advisory recorded. This unblemished run indicates diligent upkeep and the rectification of whatever minor issue caused the initial 2023 failure. The current roadworthiness status is excellent, reflecting a vehicle that has been consistently maintained to a high standard over the last three years. At roughly seven years old with 67,046 miles on the clock, the B-Class has covered an average of approximately 9,578 miles per year, which sits squarely within typical usage parameters. The mileage accumulation shows a steady, linear progression rather than erratic spikes or prolonged stationary periods. Between the January 2024 test at 47,522 miles and the January 2025 test at 56,821 miles, the car covered 9,299 miles, followed by 10,225 miles over the subsequent twelve months leading to the January 2026 test. This consistent annual accumulation points to regular, daily use without the excessive wear associated with high-mileage fleet operation or the moisture-related stagnation seen in cars left standing for months. While the official DVSA record shows no recurring structural or mechanical faults, a physical inspection remains essential to verify the condition of age-related consumables and hidden components. Buyers should closely examine the condition of the suspension bushes and coil springs for premature deterioration, a common issue on heavier compact MPVs navigating urban speed bumps. The brake discs and calipers require a thorough check for corrosion and binding, particularly given the vehicle's mileage sits at the point where original factory components typically reach the end of their service life. Inspect the exhaust system for corrosion and verify the structural integrity of the underbody and suspension mounting points, ensuring the clean MOT history aligns with the physical reality of the car.
