2017 Mercedes-Benz S-Class 2.9L Diesel · HN67 LDC

The vehicle presents a stable and positive roadworthiness profile based on the available MOT history. The most recent test conducted on 21 May 2026 at 156,338 miles passed with no defects recorded, maintaining a streak of clean results over the last five inspections. This lack of recorded failures suggests that the vehicle has been maintained to a high standard and that critical safety components are currently operating within acceptable tolerance parameters despite the high cumulative mileage. The mileage pattern indicates heavy usage for a nine-year-old vehicle, averaging approximately 17,300 miles per year. The data shows consistent accumulation, such as the 8,641 miles driven between May 2024 and May 2025 tests, and another 4,282 miles between December 2025 and May 2026. This regular, high-frequency use suggests the car is used for long-distance travel, which often prevents the issues associated with long standing periods but accelerates the wear on complex mechanical assemblies inherent to the S-Class chassis. While the MOT record is clean, a buyer must perform a thorough physical inspection of components most susceptible to high-mileage wear. The significant mileage necessitates a close check of the air suspension system for leaks or sagging, as these components rarely trigger an MOT failure until total collapse. You should also inspect the brake discs for uneven wear or thinness and examine the lower control arm bushes for tearing or cracking. Given the consistent mileage, verifying the service history regarding gearbox fluid changes and drivetrain intervals is essential to ensure the mechanical integrity matches the clean MOT record.
