2015 Mercedes-Benz S-Class 3.0L Diesel · R33 HAL

This vehicle demonstrates a stable and exceptionally clean roadworthiness trend. The most recent MOT on 16 October 2025 at 123,201 miles resulted in a pass with no defects recorded. This follows a consistent pattern of clean passes dating back to 2022, indicating a high standard of preventative maintenance and a lack of recurring mechanical failures. The mileage accumulation is consistent with the age of the vehicle. Between 10 October 2022 at 107,606 miles and 16 October 2025 at 123,201 miles, the car covered 15,595 miles over three years. This average of roughly 5,200 miles per year in recent years is lower than the overall lifetime average of 11,200 miles per year, suggesting a decrease in usage intensity. The MOT record is unusually sparse regarding defects. There are no mentions of suspension bush wear, brake disc corrosion, or exhaust emissions issues, which are common for an S-Class of this vintage and mileage. The failure on 10 October 2023 was resolved on the same day with no defects listed, implying a minor administrative or quick-fix issue rather than a structural or mechanical failure. A buyer should focus their physical inspection on components that the MOT test does not always exhaustively cover. This includes checking the condition of the air suspension for leaks or sagging and verifying the service history for gearbox oil changes. Given the lack of recorded advisories, the primary concern shifts to general wear on consumables like tyres and brake pads that may be nearing the end of their life cycle despite passing the minimum legal requirements.
