2021 Mercedes-Benz GLB 220 AMG Line Prem D 4M A 1.9L Diesel · KO21 AFZ

The vehicle has demonstrated a consistent roadworthiness record over the past two years, with all MOT tests—including the most recent one on 2025-12-02 at 42,310 miles—passing without any recorded defects or advisories. This suggests the vehicle has undergone regular maintenance and has not exhibited any significant mechanical or structural issues during the testing periods. The absence of recurring faults or advisories in the most recent tests indicates a stable condition, though an independent inspection remains essential to verify the condition of components not routinely assessed by the MOT, such as suspension wear or internal drivetrain health. The mileage progression reveals a steady usage pattern, with approximately 8,462 miles accumulated annually since the last service or significant maintenance interval. The most notable gap between tests occurred between 2024-06-26 (21,940 miles) and 2024-12-09 (25,403 miles), covering roughly 3,463 miles in just six months—a higher-than-average annual rate. This suggests the vehicle was actively driven during that period, which may have accelerated wear on consumables like brakes, tyres, and suspension components. The final stretch to the 2025-12-02 test (an additional 16,907 miles over 18 months) aligns more closely with the vehicle’s typical annual mileage, indicating a return to a moderate usage pattern. Given the clean MOT history, a buyer should prioritise an inspection of high-wear items not always captured in standard tests, such as the condition of suspension bushes and coil springs for excessive play or corrosion, particularly around wheel arches and sills. The brakes, while not flagged in tests, should be assessed for uneven wear or binding calipers, especially if the vehicle has experienced rapid mileage accumulation. Additionally, the exhaust system and underbody should be examined for signs of corrosion or leaks, as these are common failure points in vehicles of this age and mileage. The absence of advisories does not preclude internal issues such as timing belt or water pump wear, which are not MOT-tested but critical for long-term reliability.
