2006 Citroen C1 1.0L Petrol · CK56 XMT

The Citroën C1’s MOT history presents an unusual pattern of recent instability, despite its otherwise clean test records. The most recent November 2025 test at 125,758 miles passed without defects, yet the November 2024 test at 125,606 miles failed—an anomaly given the absence of recorded issues. This failure, occurring just 14 months prior to the current date, suggests either a procedural error or an undocumented but critical issue resolved shortly after. The double test in November 2023 (pass/fail at 119,219 miles) further complicates the picture, as both entries lack defects, implying the failure may have stemmed from administrative rather than mechanical causes. The November 2022 test at 112,212 miles passed cleanly, reinforcing that the car’s core systems were functional at that stage. Without defects logged, there’s no evidence of worsening mechanical trends, but the repeated failures raise questions about whether the vehicle’s condition was ever properly scrutinised. The mileage accumulation aligns closely with typical usage for a 20-year-old vehicle, averaging around 6,288 miles per year—a figure consistent with moderate, steady driving. The gap between the 2022 and 2023 tests (6,997 miles over 11 months) and the subsequent 2023–2024 interval (6,397 miles over 12 months) suggests no periods of prolonged inactivity or excessive wear. The slight drop to 125,606 miles in November 2024 before rising again to 125,758 by November 2025 is negligible, indicating minimal recent use or potential odometer manipulation. The absence of mileage spikes or prolonged dormancy implies the car was driven regularly, though the lack of defects in failed tests is atypical and warrants closer examination of service records. Given the MOT’s inconsistencies, a buyer should prioritise a thorough inspection of structural and safety-critical components, particularly those prone to silent degradation in older vehicles. The suspension—including coil springs, anti-roll bars, and bushings—should be checked for wear or corrosion, as these are common failure points in high-mileage Citröen models. Braking performance must be verified, as binding calipers or uneven disc wear often go unnoticed until late stages. The exhaust system, including mounts and catalytic converter integrity, should be assessed for leaks or excessive vibration, while the underbody must be inspected for structural rust, especially around wheel arches and sills. The repeated MOT failures without defects imply either a history of last-minute repairs or potential neglect of non-MOT-tested areas, such as fluid leaks or electrical faults. A pre-purchase inspection by a qualified mechanic is strongly advised to confirm the absence of hidden issues.
