2017 Mercedes-Benz GLS 3.0L Diesel · PF67 DLV

The 2017 Mercedes-Benz GLS presents a clean roadworthiness status with a stable maintenance trend. The most recent test on 27 February 2026 at 115,956 miles passed with no defects recorded, continuing an unbroken sequence of passes since at least 2022. The absence of any advisories across five consecutive annual tests indicates the vehicle has not required flagged attention on brakes, suspension, emissions, or structural corrosion during this period. Annual mileage has averaged roughly 12,884 miles, which is high for a nine-year-old luxury SUV but consistent rather than erratic. The records show steady accumulation: 61,760 miles in March 2022, 78,991 by March 2023, 94,935 by March 2024, 104,686 in February 2025, and 115,956 by February 2026. No significant standing gaps or sudden jumps appear. The clean test history at each interval suggests the previous keeper kept the vehicle serviced to a standard that satisfied DVSA pass criteria without deferred consumable replacement surfacing as advisories. A buyer should still commission an independent inspection despite the unblemished MOT trail. The GLS uses complex air suspension and multi-link rear geometry that can degrade without triggering a test failure, particularly at 115,000 miles. Examine the front lower suspension bushes, rear coil springs, and brake disc wear for uneven scoring. Check underneath for early structural corrosion around subframe mounts, as MOT passes do not certify absence of developing rust. Given the high mileage and luxury drivetrain, verify service book stamps match the odometer steps above. Confirm the transfer case and automatic gearbox fluid changes were completed on schedule. The MOT record proves legal roadworthiness but reveals nothing about internal mechanical wear invisible to a roadside test.
