2017 MERCEDES-BENZ S-Class3.0L DIESEL

The vehicle currently maintains a roadworthy status, showing a stable maintenance trend over the last two years. The most recent test in March 2026 at 152,583 miles passed, although the tester noted that emissions had to be cleaned to achieve an acceptable reading. This follows two clean passes in late 2024 and early 2025, indicating that the primary mechanical and safety components have met minimum standards despite the high mileage. The mileage profile reflects heavy usage for a nine-year-old luxury saloon, averaging approximately 17,000 miles per annum. A significant period of activity occurred between November 2025 and March 2026, where the car covered over 14,000 miles in just four months. This consistent usage suggests regular long-distance driving rather than neglect, which typically accelerates wear on drivetrain components and complex suspension systems compared to city driving. The fitting of a new engine cover and undertray in October 2024 at 132,447 miles suggests a proactive repair or a response to under damage. A buyer should specifically investigate the oil leak identified during the March 2024 test at 120,972 miles. While it was described as not excessive at the time, high-mileage Mercedes engines often suffer from weeping gaskets or oil seals that can require monitoring over time. The emissions issue in March 2026 also indicates potential carbon buildup or sensor degradation that warrants a diagnostic check to ensure long-term efficiency. Given the mileage, a thorough inspection of the air suspension components and control arm bushings is essential, as these parts are prone to fatigue beyond the 150,000-mile mark.
