2017 Mercedes-Benz S-Class 3.0L Diesel · YU52 AFS

The vehicle presents a strong roadworthiness profile, having passed its most recent inspection in July 2025 with no recorded defects. The maintenance trend is exceptionally stable, as the car has achieved three consecutive clean passes since a single failure in mid-2023. The absence of defects in the last two annual tests suggests that the vehicle is being maintained to a high standard and meets current safety requirements without immediate intervention. The mileage pattern is remarkably consistent for a nine-year-old vehicle, averaging approximately 9,450 miles per year. There was a notable increase in usage of over 16,000 miles between July 2023 and June 2024, followed by a more standard interval of 15,335 miles leading up to the most recent test. This steady accumulation indicates the car is being used regularly rather than sitting for long periods, which is generally beneficial for the seals and mechanical components of a luxury German saloon. While the MOT history is clean of recurring faults, a buyer should focus their physical inspection on high-wear areas typical of S-Class at this mileage. Given the 85,000-mile mark, the air suspension system and control arms should be tested for leaks or bushing wear, as these are common points of failure. Additionally, the brake discs and pads should be inspected for remaining life, as the MOT only checks for minimum thickness rather than overall component health.
