2010 Mercedes-Benz CLS 3.0L Diesel · YC10 PYY

The vehicle remains roadworthy but the maintenance history reveals a worsening trend regarding neglected braking and suspension components. While it passed the most recent test in February 2026 at 120,978 miles, the tester identified new issues including thin front brake pads and play in the nearside front suspension arm ball joint. The persistence of corroded and greased brake pipe issues across the last three years suggests that the previous owners are only addressing faults upon inspection failure rather than performing proactive preventative maintenance. The mileage pattern averages approximately 7,500 miles per year, which is consistent with a 16-year-old luxury saloon. There was a significant jump of over 10,000 miles between February 2023 and February 2024, followed by another 10,400 miles in the following year. This consistent usage indicates the car is driven regularly, which explains the accelerated wear on rubber components and metal brake lines, but also means the vehicle has been subjected to the environmental-related corrosion seen on the chassis. A buyer must prioritise a thorough inspection of the entire braking system, as corrosion on the pipes and hoses has been a recurring failure point since at least 2023. The presence of grease on these lines is particularly concerning as it often indicates an attempt to hide leaks or degradation from the tester. Furthermore, the recent appearance of play in the ball joint at 120k miles suggests that the suspension bushings and joints are reaching the end of their service life. The recurring oil leak noted in 2024 also requires physical verification to ensure it is not a significant engine seal failure that could compromise the long-term reliability of the drivetrain.
