2016 Mercedes-Benz S-Class 3.0L Diesel · KD16 ACO

The 2026‑04‑28 MOT at 53,728 miles recorded a pass with no defects, confirming that the vehicle is presently roadworthy. The maintenance record shows a stable to improving trend, as the most recent test resolved earlier issues such as the 2024 suspension arm failure and the 2023 brake fluctuation, with no new defects reported. The mileage trajectory over the past eight years reveals a low average annual usage of roughly 5,373 miles, yet the rate of accumulation has accelerated markedly since 2022, rising from 27,783 miles in May 2022 to 53,728 miles by April 2026, an increase of 25,945 miles in just over four years, or about 6,486 miles per year. Periods such as 2018‑2021 show slower growth, indicating periods of reduced use, while the rapid mileage gain in the last four years suggests increased operational demand. A buyer should therefore focus on the recurring offside front suspension arm ball joint wear, the slight play noted in the steering rack inner joint, and the history of fluctuating front service brakes, inspecting suspension bushes, coil springs, ball joints, steering rack condition, brake discs, pads and calipers for binding or excessive wear, and checking for structural rust or corrosion on chassis components.
