2016 Mercedes-Benz S-Class 3.0L Diesel · YF66 ACJ

The vehicle currently maintains a roadworthy status, having passed its most recent MOT on 24 June 2025 with 181,131 miles and no recorded defects. The overall maintenance trend appears stable following a single failure in June 2024. Since that failure at 142,964 miles, the car has undergone two consecutive clean tests, suggesting that any previously identified issues were addressed and the vehicle is currently operating within the required safety parameters. The mileage profile is high for a ten-year-old S-Class, averaging approximately 18,000 miles per year. The data shows a significant surge in usage recently, with 22,604 miles covered between the July 2024 and January 2025, and another 15,386 miles in the five months leading up to the June 2025 test. This high-frequency use puts considerable strain on heavy-duty components, particularly the drivetrain and air suspension, though the consistent passing results indicate the vehicle is being used regularly rather than left to sit and degrade. A buyer should prioritize a physical inspection of the air suspension system and rubber bushings, as high-mileage Mercedes luxury cars often suffer from perished strut bellows and control arm wear. Given the rapid accumulation of mileage, the brake discs and calipers should be checked for excessive thinning or uneven wear resulting from heavy use. While the MOT record shows no current structural corrosion, a close look at the underbody for road-salt wear is necessary to ensure that the high mileage has not led to accelerated metal fatigue on the chassis.
