2018 Mercedes-Benz C 1.6L Diesel · WM18 AEB

The vehicle’s most recent MOT on 2025-04-28 at 76,809 miles recorded a pass with no defects, but a prior test on 2025-04-26 at 76,803 miles showed a failure with no recorded defects. This suggests either a data inconsistency or a minor issue resolved within 6 days. Subsequent tests from 2024-03-28 (57,594 miles) and earlier were all passes with no defects, indicating a stable maintenance trend over the past four years. The absence of structural, suspension, or braking defects in these records implies the car has been well-maintained, though the abrupt failure in early 2025 warrants scrutiny. The mileage progression aligns with typical annual usage, averaging ~9,600 miles per year. However, a significant jump from 57,594 miles (2024-03-28) to 76,809 miles (2025-04-28) reflects accelerated usage over 13 months, which could accelerate wear on components like brake discs, suspension bushes, and exhaust systems. No gaps in testing are evident, and the clean history from 2022-03-17 (24,477 miles) to 2024-03-28 suggests consistent monitoring. The lack of advisories or recurring issues in earlier tests supports the conclusion that the vehicle has been subject to regular, if not rigorous, upkeep. A buyer should inspect the suspension for worn bushes or coil springs, as rapid mileage increases can exacerbate these issues. The rear brakes, given their susceptibility to binding or uneven wear, should be checked for corrosion or uneven pad thickness. The exhaust system, particularly the catalytic converter, merits attention due to potential emission-related faults. While the MOT records show no structural rust or major mechanical failures, the abrupt 2025 failure—despite no defects—highlights the need for a pre-purchase inspection to verify the car’s mechanical integrity beyond documented tests.
