2020 Mercedes-Benz GLS 400 AMG Line Prem D 4MAT A 2.9L Diesel · NL20 PWU

The vehicle presents a high standard of roadworthiness, evidenced by the most recent MOT on 13 March 2026 at 37,763 miles which passed with no recorded defects or advisories. This indicates a stable maintenance trend where the vehicle has consistently met regulatory standards without the accumulation of mechanical or structural failures. The history suggests a proactive approach to maintaining the platform. The mileage pattern is consistent with low-intensity usage for a vehicle of this age, averaging approximately 6,300 miles annually. Between the March 2025 test at 31,758 miles and the March 2026 test at 37,763 miles, the vehicle covered 6,005 miles. This steady accumulation suggests no excessive wear on heavy-duty components such as the drivetrain or air suspension system. However, the presence of engine undertrays and covers noted in the 2024 and 2025 tests means that visual access to the lower chassis was likely restricted during those specific inspections. A buyer should conduct a physical inspection of the undercarriage to ensure no hidden corrosion or fluid leaks have developed beneath the undertrays, as these components can trap moisture and road faults. Given the low mileage, the focus should remain on the condition of rubber-based components like suspension bushes and brake hoses, which can age over time regardless of distance driven. The 2025 record notes that a child seat prevented a full inspection of the adult seat belt, so the belt mechanism should be verified manually to ensure it operates correctly and is free of fraying.
