2009 Mercedes-Benz E 3.0L Diesel · WR09 OSB

The roadworthiness of this Mercedes-Benz is currently questionable due to a pattern of inconsistent MOT pass results. While the most recent test on 7 November 2023 at 156,936 miles resulted in a failure without specific recorded defects, the history suggests a cycle of reactive maintenance rather than proactive care. The trend does not qualify as stable, as the vehicle repeatedly fails tests shortly before or after a pass, indicating that issues are addressed only when forced by a legal requirement rather than through a consistent schedule of mechanical inspections. The mileage profile is consistent with a 17-year-old vehicle, averaging approximately 9,200 miles per year. However, the data reveals periods of high usage followed by significant gaps in testing frequency. Between July 2021 and September 2022, the car covered over 12,000 miles, whereas it covered only roughly 9,000 miles between August 2022 and November 2023. The gap of nearly three years since the last recorded MOT in November 2023 means the vehicle is currently operating on an expired certificate or has been sitting stationary, which increases the risk of rubber-based components degrading and brake calipers seizing. A buyer must conduct a thorough physical inspection of the chassis and suspension components, as the record shows failures without detailed notes which often mask intermittent mechanical faults. Given the age and mileage, priority should be placed on inspecting corrosion on the subframe and wish arms, which are common failure points on this model. The inspector should also check for signs of uneven brake wear and worn suspension bushes, as the lack of recorded advisories in previous passes suggests that minor wear issues are being ignored until they reach a point of failure.
