2021 Mercedes-Benz GLB 220 AMG Line Prem D 4M A 1.9L Diesel · T28 FNY

The GLB 220 presents a stable and exemplary maintenance trend, evidenced by a flawless MOT record with zero advisories across all three tests. The most recent examination on 3 September 2025 at 30,016 miles passed without a single defect, confirming the vehicle currently meets all structural and mechanical roadworthiness standards. This consistent pass rate indicates a diligent ownership history with no recurring mechanical faults. The mileage accumulation tells a distinct story of exceptionally light use. Between the March 2024 test at 25,210 miles and the March 2025 test at 29,142 miles, the vehicle covered 3,932 miles. The subsequent six months leading to the September 2025 test saw a mere 874 miles added. Such low annual mileage, averaging roughly 6,000 miles per year, points to short-trip commuting or extended periods of inactivity rather than sustained motorway driving. Despite the pristine MOT history, the unusually low recent mileage warrants a specific physical inspection. Short journeys and prolonged standing can cause issues that a standard MOT does not always capture. Inspect the brake discs for surface corrosion and check the tyres for flat-spotting or uneven wear, as low-speed, short-distance driving prevents the components from reaching optimal operating temperatures to clear moisture and debris. Examine the suspension bushes and coil springs for perishing, as vehicles sitting for extended periods can develop deterioration that only manifests at higher speeds. A thorough test drive will verify the 4Matic drivetrain and diesel particulate filter are functioning correctly under load. While the paperwork suggests a well-maintained vehicle, the physical reality of low-mileage diesel operation requires a hands-on assessment to rule out the typical ailments of a car that has spent too much time stationary.
