2016 Citroen C1 1.0L Petrol · GC16 SCX

The Citroën C1’s most recent MOT test on January 9, 2026, at 54,604 miles confirms it passed without any defects, though the record reveals an unusual pattern of repeated failures at the same mileage intervals in both 2024 and 2025. Each January test—whether passed or failed—occurred at precisely 43,879 and 48,205 miles, suggesting a deliberate or coincidental alignment with service intervals. The absence of defects in the latest pass indicates no immediate mechanical failures, but the history of repeated failures at identical mileages warrants scrutiny of components prone to predictable wear, such as suspension bushes or brake calipers, which often degrade at consistent intervals. The lack of advisories or advisories resolved in prior tests also suggests no ongoing issues were addressed between tests, though this could imply either diligent maintenance or neglect of pre-MOT checks. The vehicle’s mileage progression of roughly 5,460 miles annually over the past decade is unusually low for a car of this age, particularly given the repeated MOT tests at fixed intervals. Between January 2024 and January 2025, the mileage increased by just 4,326 miles—less than half the average annual figure—indicating prolonged periods of inactivity. This could point to storage conditions that may have accelerated corrosion risks, especially in suspension components, wheel arches, or underbody panels. Conversely, the consistent mileage jumps of around 4,300 miles between tests suggest the car was likely driven only for MOT purposes, which may not reflect real-world usage patterns. Buyers should verify whether the vehicle has been stored indoors or exposed to moisture, as prolonged idling can exacerbate rust development in critical areas. Given the repeated failures at identical mileages, the most critical areas for an in-person inspection should focus on suspension integrity and braking systems. The rear brakes were flagged in prior tests, though the exact nature of the failure isn’t specified—common issues in this class of vehicle include binding calipers, worn pads, or seized wheel cylinders. Suspension bushes, particularly at the rear trailing arms or subframe mounts, are another high-risk area given their tendency to degrade predictably over time. Structural corrosion, particularly around the wheel arches, sills, or exhaust system, should be checked for signs of pitting or thinning, as the low mileage suggests prolonged exposure to environmental factors. The absence of advisories in recent tests does not preclude hidden issues, so a thorough examination of fluid levels (brake, power steering, coolant) and underbody components is essential to confirm no deferred maintenance exists.
