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

The vehicle demonstrates stable roadworthiness, with no defects recorded in its most recent September 2025 MOT at 39,989 miles. The prior July 2024 test at 27,888 miles also showed no issues, confirming a consistent maintenance pattern. No advisories or failures indicate the car has been well-maintained, with no emerging mechanical concerns. The absence of defects across two consecutive tests suggests the owner prioritised regular servicing, though the limited data does not confirm long-term reliability beyond these records. The mileage progression aligns with typical usage for a five-year-old vehicle, averaging approximately 8,000 miles annually. The 12,101-mile increase between July 2024 and September 2025 reflects steady driving rather than prolonged inactivity, reducing concerns about component degradation from standing. However, the sparse MOT history—only two tests—limits insight into potential wear trends. A buyer should verify if additional service records exist to confirm ongoing maintenance, as the current data does not capture intermediate issues. A physical inspection should focus on suspension components, including bushes and coil springs, which can degrade over time without MOT testing. Brake systems, particularly calipers and discs, warrant scrutiny for binding or uneven wear, as these often develop gradually. Structural corrosion, especially in lower body panels, should also be checked, as it may not appear in MOT records. While the car’s MOT history shows no faults, these areas remain critical for long-term safety and should be assessed by a qualified mechanic.
