2010 Mercedes-Benz C 3.0L Diesel · SP10 MKX

The vehicle presents a concerning roadworthiness profile with a maintenance trend that appears increasingly reactive as it nears high mileage. While the most recent test on December 29,2022 at 163,405 miles was a pass, it followed an immediate failure for safety-critical defects. The presence of corroded brake pipes covered in grease and a defective rear parking brake lever indicates that essential braking components were only addressed after failing an inspection, rather than through preventative maintenance. At 163,405 miles over sixteen years, the car maintains an average of approximately 10,213 miles per year, which is consistent with typical usage for a vehicle of this age. The history shows a steady interval of annual testing, with roughly 6,000 to 7,000 miles covered between tests from 2019 and 2022. However, the transition from a clean record at 150,000 miles to multiple failures shortly after suggests the vehicle is now experiencing accelerated wear on mechanical assemblies. A buyer must conduct a thorough physical inspection of the braking system and suspension geometry. The 2021 test flagged worn suspension arm bushes on both front sides, and the 2022 failure highlighted corrosion on brake lines, which suggests the structural integrity of metal components may be deteriorating. Particular attention should be paid to the grease found on the brake pipes, as this is often used to mask significant surface rust from the own. The parking brake mechanism should also be tested to ensure the previous defect has been fully rectified rather than merely adjusted.
