2021 Mercedes-Benz GLB 220 AMG Line Prem D 4M A 1.9L Diesel · WR71 ACX

The 2021 Mercedes-Benz GLB 220 AMG Line Premium diesel presents as roadworthy with a stable maintenance trend. The most recent test on 23 March 2026 at 13,888 miles passed with no defects recorded, continuing an unbroken clean MOT run across all three available entries. The mileage pattern shows exceptionally light use for a five-year-old vehicle. From the 17 December 2024 test at 7,865 miles, the car covered just 1,033 miles to the 2 April 2025 test at 8,898 miles, then 5,000 miles by March 2026. Annual averages sit near 2,778 miles. Such low totals suggest prolonged standing periods rather than steady daily driving, though the record itself is sparse and shows no advisories, failures, or gaps requiring explanation. A buyer should still commission an in-person inspection of suspension bushes, brake discs, and underbody corrosion despite the clean history. Low-mileage cars left idle often develop perished rubber components and surface rust on structural members that a pass-with-no-defects test will not capture if below test thresholds. The drivetrain and 4Matic system warrant a cold-start check for binding calipers or fluid degradation from disuse. Given three consecutive passes and no recorded advisories, prior keepers appear to have met statutory test requirements without neglect. The absence of tyre, wiper, or exhaust emissions flags implies basic upkeep was maintained, but the limited sample means pre-purchase scrutiny of consumable condition remains prudent.
