2017 Mercedes-Benz C 2.1L Diesel · FG67 WNJ

The 2017 Mercedes-Benz C-Class presents a stable and clean maintenance trend, culminating in a pass at its most recent MOT on 23 February 2026 at 101,196 miles with zero defects recorded. Prior to this, the vehicle failed its test on 18 February 2026 at 100,870 miles, though the record indicates no specific defects were logged for that failure. The subsequent pass just five days later suggests the issue was promptly rectified, likely a minor fault requiring immediate attention before the retest. The absence of any recorded advisories or defects across the entire history indicates a well-maintained vehicle that has consistently met roadworthiness standards. The mileage accumulation aligns closely with typical usage for a vehicle of this age, averaging roughly 11,244 miles per year. Between the May 2022 test at 46,043 miles and the August 2023 test at 70,403 miles, the car covered 24,360 miles in just over twelve months, indicating a period of heavier use or regular long-distance commuting. Following this, the mileage increased by only 30,793 miles over the subsequent two and a half years until the February 2026 tests, reflecting a significant reduction in annual mileage. The recent gap between the failed and passed tests shows a minimal accumulation of 326 miles, consistent with a short drive to the retest facility. Despite the pristine MOT record, a buyer should conduct a thorough physical inspection of the vehicle's structural and mechanical components, particularly given the unexplained February 2026 failure. Investigate the condition of the brake discs and pads, as well as the suspension bushes and coil springs, which endure significant stress at this mileage. The near-100,000-mile mark demands a close examination of the exhaust system for corrosion and the drivetrain for any excessive play or fluid leaks. While the paperwork suggests diligent upkeep, the lack of recorded defects does not preclude the need for a professional evaluation of the underbody and engine bay to verify the vehicle's long-term structural integrity.
