MERCEDES-BENZ S-Class2015 · 3.0L DIESEL

The vehicle remains roadworthy, but the maintenance trend shows a persistent failure to address developing suspension defects. While the most recent test in August 2025 at 67,314 miles passed, the offside front lower suspension arm ball joint remained flagged with slight play for three consecutive years. This indicates that the previous owners have monitored the fault rather than replacing the worn component, leading to a recurring mechanical weakness that has not been rectified. The mileage profile is consistent with a low-use vehicle of this age, averaging approximately 6,100 miles per annum. Between September 2022 at 56,164 miles and August 2025 at 67,314 miles, the car covered roughly 11,150 miles over three years. This low annual mileage generally reduces wear on drivetrain components, but it often leads to rubber-based parts degrading and cracking over time, which likely aligns with the suspension issues observed on this 11-year-old S-Class. A buyer must prioritize a thorough inspection of the front suspension geometry. The recurring advisory on the offside front lower suspension arm ball joint since 2022 suggests that the wear is progressive, and leaving it unaddressed will lead to uneven tyre wear and handling instability. Furthermore, the record shows a pattern of neglecting tyre maintenance, with multiple advisories for tyres worn to the legal limit or failing requirements in 2024 and 2025. The buyer should check the current tread depth and alignment of all four tyres to ensure no tracking issues have been caused by the faulty ball joint.
