2010 Citroen C1 1.0L Petrol · YR10 YPP

The vehicle remains roadworthy but the maintenance history reveals a worsening trend regarding structural corrosion. While the most recent MOT test in December 2025 at 120,191 miles passed, the tester identified widespread corrosion on the rear sub-frame and all four brake pipes. This represents a progression from a critical failure in November 2024 where the offside rear integral body structure was flagged for significantly reduced rigidity. Although the car has since passed, the persistence of deep surface corrosion across multiple components indicates an active degradation process. The recorded mileage of 120,191 miles reflects a consistent average of approximately 7,500 miles per year, which is typical for a sixteen-year-old city car. There is a notable anomaly in usage between December 2023 and November 2024, where the vehicle covered only 5,096 miles in eleven months. This low-intensity use suggests long periods of standing, which often accelerates the oxidation of metal components like brake lines and frames due to a lack of mechanical cleaning, as seen in the subsequent failures. A buyer must conduct a thorough physical inspection of the sub-frame and brake line connections to ensure the corrosion has not progressed beyond the advisory stage since the last test. The recurring mention of grease or material covering corroded pipes suggests previous owners may have attempted to mask rust from inspectors rather than replacing the failing lines. Attention should be paid to the structural integrity of the rear suspension mounting points and the condition of the exhaust hangers, as these areas are common points of failure for this specific model.
