2021 Mercedes-Benz S 400 L AMG LN Prm+exec D 4M A 2.9L Diesel · SN21 ODL

The vehicle maintains a high standard of roadworthiness, evidenced by a consistent history of clean passes. The most recent test conducted on 9 April 2026 at 34,161 miles resulted in no recorded defects, continuing a trend of mechanical stability across the last three years. This consistency suggests that the previous owners have maintained the vehicle effectively and that the primary components are currently operating within expected performance parameters. The mileage pattern is remarkably consistent for a five-year-old vehicle, averaging approximately 6,800 miles per annum. The data shows a period of low usage between April 2024 at 30,606 miles and October 2024 at 30,693 miles, followed by a steady increase to 32,220 miles in May 2025 and finally to April 2026. This low annual mileage typically indicates reduced wear on heavy-duty components, suspension bushings, and brake assemblies compared to high-mileage examples. Because the MOT record shows no advisories or failures, a physical inspection should focus on components not fully covered by the annual DVSA test-related items. A buyer should verify the air suspension system for any signs of leaking or sagging, as these components can age over time on this model regardless of mileage. Given the low usage, checking the brake discs for surface corrosion or pitting is also advisable, as vehicles that sit for longer periods can develop uneven wear on the rotors.
