2017 Mercedes-Benz S-Class 3.0L Diesel · MK17 AAN

The vehicle currently holds a clean roadworthiness status, following a successful MOT pass in April 2026 at 116,122 miles. The maintenance trend shows an improving trajectory after a period of mechanical concern in 2024. While the 2024 test identified several defects, the two most recent inspections recorded no faults, suggesting the previous owner addressed the flagged issues and subsequently maintained the vehicle to a higher standard. The mileage profile reflects consistent high-frequency use, averaging approximately 13,000 miles per year over its nine-year life. A significant spike in usage occurred between April 2023 and April 2024, where the car covered over 14,000 miles in a single year. Since then, the accumulation has slowed to a more moderate rate of roughly 5,700 miles annually. This high-mileage typically puts accelerated wear on the complex air suspension components and drivetrain bushings inherent to the Mercedes S-Class chassis. A buyer should conduct a thorough inspection of the suspension geometry, as the 2024 test specifically flagged play in the offside front lower suspension arm ball joint and a deteriorated rear prop shaft flexible coupling. Although these were cleared in later tests, the rubber-based components on this heavy-weight vehicle are prone to premature cracking. Verify the condition of the tyres and alignment, as the 2024 record noted uneven wear and sidewall damage, which can indicate underlying geometry issues or poor consumable maintenance.
