2021 Mercedes-Benz S 500 L AMG Line Prm+mhev 4M A 3.0L Hybrid electric · KET 4N

The vehicle maintains a clean record of roadworthiness, with the most recent MOT on 9 March 2026 resulting in a pass with no defects recorded. Although the vehicle failed its initial attempt on the same day, the lack of recorded defects suggests a minor administrative or testing error rather than a mechanical failure. This pattern indicates a stable maintenance history, as the car has cleared its annual inspections without any advisories or component failures over the past three years. The current mileage of 50,534 miles over a five-year period aligns with standard usage patterns for a luxury saloon of this class. The vehicle has averaged approximately 10,100 miles per annum, suggesting consistent use rather than prolonged periods of inactivity or excessive high-mileage motorway commuting. The steady accumulation of mileage from the 2024 test through to the 2026 inspection confirms the car has remained in regular service, which typically helps prevent the issues associated with long-term storage, such as seized brake calipers or perished rubber seals. Prospective buyers should focus their physical inspection on the complex air suspension system and electronic components, as these are not always fully captured by the standard MOT test. While the MOT history is clean, the sophisticated nature of the S-Class drivetrain and chassis requires verification of service documentation beyond the annual test. Check the condition of the brake discs and pads for uneven wear, as the vehicle weight can accelerate consumable degradation. Confirm that the tyres match the premium specifications required for this model, as the absence of MOT advisories implies the previous owner maintained the vehicle to a high standard.
