2013 Mercedes-Benz S-Class 3.0L Diesel · KM13 BVC

The vehicle currently maintains a stable roadworthiness status, showing a clearly improving maintenance trend. The most recent MOT test conducted in March 2026 at 54,253 miles resulted in no defects recorded, following three consecutive years of clean passes. This indicates that the mechanical and safety-related issues identified in previous years have been addressed and the car is currently meeting all minimum legal safety standards. The mileage profile is notably low for a thirteen-year-old S-Class, averaging approximately 4,173 miles per year. There is a significant gap in usage between March 2021 and September 2022, where the vehicle covered only 1,661 miles in over sixteen months. Since then, usage has increased, with nearly 8,000 miles recorded between September 2022 and March 2026. While low mileage generally suggests less wear on the engine and drivetrain, long periods of standing can sometimes lead to the degradation of rubber-based components and fluid seals. A buyer should focus their physical inspection on the areas flagged during the 2021 test at 30,354 miles. The tester previously identified pitted front brake discs, an oil leak, and play in both front wheel bearings. Although the recent tests show no current faults, a physical inspection must verify that the oil leak has not recurred and that the wheel bearings remain silent and secure. Given the age of the vehicle and the low mileage, checking for perished suspension bushes and dry seals is essential, as these components often fail through age rather than distance driven.
