2015 Mercedes-Benz C 2.1L Diesel · BT15 ACO

The vehicle’s most recent MOT on 2026-02-04 at 81,407 miles resulted in a pass with no defects recorded, indicating a stable maintenance trend. However, the preceding test on 2026-01-30 at 81,403 miles failed without recorded defects, suggesting a potential administrative or procedural anomaly. Subsequent annual tests from 2023 to 2025 showed consistent passes with no defects, confirming a generally reliable maintenance history. The absence of critical issues in the latest test implies the car is currently roadworthy, though the January 2026 failure warrants scrutiny for unrecorded advisories or technical oversights. The vehicle’s mileage of 81,407 miles over 11 years equates to an average of 7,401 miles annually, aligning with typical usage for its age. MOT tests have been conducted consistently each year, with no gaps exceeding 12 months, reflecting responsible ownership. The minimal mileage variation between tests—just 4 miles between the January and February 2026 assessments—suggests the car has been driven infrequently in recent months, potentially indicating storage or reduced usage. This pattern reduces wear on consumables but may increase risks of component degradation from inactivity, such as rubber seals or fluid contamination. A physical inspection should prioritise components prone to gradual wear, including suspension bushes, coil springs, and brake calipers, as these are common failure points in older vehicles. The absence of corrosion or structural issues in the MOT records is reassuring, but buyers should verify the exhaust system for leaks or rust, which can develop unnoticed. Additionally, checking the brake discs for uneven wear and ensuring the steering system operates smoothly without play is advisable. While the MOT history shows no critical faults, the January 2026 failure—despite no defects recorded—highlights the importance of a thorough pre-purchase examination to confirm the car’s mechanical integrity.
