2017 Mercedes-Benz S-Class 3.0L Diesel · KT66 EBG

The vehicle presents a stable roadworthiness profile based on the most recent inspection data. The latest test conducted on 21 December 2025 at 85,367 miles showed no recorded defects, indicating that previous issues identified by the tester have been addressed. This represents an improving trend compared to the January 2025 test, where the vehicle was flagged for tyre wear and a child seat-related obstruction. The mileage pattern is consistent with a nine-year-old luxury saloon, averaging approximately 9,500 miles per annum. There is a clear gap of 21,018 miles between the December 2021 test at 47,741 miles and the January 2024 test at 68,759 miles, followed by another 16,627-mile interval leading to the early 2025 inspection. This steady accumulation suggests the car has been used regularly, which generally helps prevent seal degradation and component corrosion associated with long stationary periods. A buyer should focus their physical inspection on the brakes and tyres. The January 2025 record noted both nearside and offside front tyres were being close to the legal limit and showing edge wear, which often indicates an alignment issue or worn suspension bushes. Furthermore, the January 2023 test flagged thin rear brake pads. While the 2025 test passed without defects, the remaining life of the pads and the condition of the discs should be verified to ensure no binding persists. Given the age and model of this S-Class, a thorough check of the air suspension components for leaks is also advisable, as these are not covered by standard MOT testing.
