2009 Mercedes-Benz 350 2.6L Diesel · KY59 FYE

The vehicle remains roadworthy but the maintenance history shows a worsening trend regarding mechanical wear and de-conditioning. While the most recent test in August 2025 at 139,667 miles passed, it introduced new concerns such as an oil leak and misting on the nearside front shock absorber. These issues follow a pattern of escalating corrosion and suspension wear that has remained unaddressed across multiple testing cycles, suggesting that the owner is addressing only the minimum legal requirements rather than performing proactive preventative maintenance. At 139,667 miles, the car has averaged approximately 8,200 miles per year, which is consistent with typical usage for a seventeen-year-old luxury vehicle. The data shows steady usage patterns, with roughly 7,000 miles covered between July 2023 and August 2024, and another 7,300 miles between August 2024 and August 2025. This consistent mileage indicates the vehicle is not sitting for long periods, but the age has clearly accelerated the degradation of rubber components and metal lines under the chassis. A buyer must prioritize a thorough inspection of the braking system and suspension geometry. The record flags both rear brake pipes as corroded and covered in grease in both 2024 and 2025, which often indicates an attempt to hide structural pipe rust that could lead to fluid failure. The play in the nearside front lower ball joint noted in 2024 and the new misting shock absorber in 2025 suggest the front suspension is nearing the end of its functional life. The reported oil leak in the latest test also requires immediate investigation to determine if it is a minor seal weep or a more significant engine component failure.
