2017 Mercedes-Benz C 2.1L Diesel · GD66 XEW

The vehicle remains roadworthy, though the maintenance trend shows a transition toward reactive repairs on wear-related components. The most recent test in January 2026 at 115,082 miles identified a defect regarding the rear anti-roll bar pin or bush. While this did not result in a failure, it marks the beginning of recorded issues with the vehicle's suspension geometry after several years of clean inspections. The vehicle reflects a high mileage profile for its age, averaging approximately 12,800 miles per year. The usage is consistent and heavy, as evidenced by the 10,000 miles covered between the January 2024 and 2025 tests, and another 7,135 miles recorded between the 2025 and 2026 tests. This steady high-mileage accumulation suggests the car has been used for regular motorway commuting rather than short-city trips, which tends to accelerate the degradation of rubber components and braking hardware. A buyer should focus their physical inspection on the rear suspension assembly and braking system. The January 2025 test at 107,947 miles flagged thin rear brake pads and pitted or scored discs, indicating the previous owner waited until components were significantly worn before replacement. Given the recent advisory on the anti-roll bar bush in 2026, a thorough check for excessive play in the control arms and bushings is necessary to prevent uneven handling. The high mileage also necessitates a close look at the drivetrain and underbody for fluid leaks, as these components often reach their service limit around this interval.
