2013 Mercedes-Benz C 2.1L Diesel · AY63 ULL

The vehicle is currently roadworthy but the maintenance trend shows a shift from clean inspections to mechanical degradation. While the most recent test in March 2026 at 175,678 miles passed, the tester flagged a low-effort park brake, corroded brake pipes, and a non-excessive oil leak. These entries represent a departure from the clean records seen in previous years, indicating that the vehicle is now entering a phase where age-related wear requires proactive attention. The mileage profile is consistently high, averaging approximately 13,500 miles per year over the thirteen-year period. There was a particularly significant burst of use between March 2025 and March 2026, where the car covered 15,759 miles in just twelve months. This rapid accumulation explains the transition from the thin nearside rear brake pads noted in 2025 to the subsequent brake pipe corrosion in 2026. The high mileage suggests frequent motorway use, which typically places significant strain on the drivetrain and suspension components. A buyer must conduct a thorough physical inspection of the braking system and the underbody. The corrosion on the brake pipes recorded in March 2026 is a critical item, as pipe degradation can lead to hydraulic failure if left unaddressed. The low-effort park brake should be tested for mechanical play to ensure the cables or the mechanism are not seizing. Furthermore, the oil leak identified in the latest test should be traced to determine if it is a simple gasket seal or a more significant engine issue, given the high-mileage context.
