2013 Citroen C1 1.0L Petrol · ML63 OVT

The vehicle's roadworthiness shows a worsening trend in mechanical and safety-critical components. The most recent test on 29 December 2025 resulted in a failure due to a dangerous parking brake efficiency level of less than 50%. This failure follows a series of advisories and failures regarding braking systems and suspension components. The tester also flagged multiple major defects including inoperative lighting and an ineffective windscreen wiper. With 159,559 miles recorded over 13 years, the vehicle averages approximately 12,274 miles per year. This represents high usage for a small city car, which correlates with the frequent advisories for wear and tear on consumables and structural elements. The record provides a consistent annual testing history, though the mechanical issues appear to be accumulating rather than being resolved through preventative maintenance. A buyer should prioritise a thorough inspection of the braking system and chassis. The record shows a persistent pattern of corrosion on the rear brake pipes, which was noted in 2021, 2023, 2024, and 2025. The recent dangerous failure of the parking brake suggests the braking system requires immediate professional assessment. Additionally, the recurring advisories regarding exhaust leaks since 2022 and ongoing concerns with suspension ball joints and bushes indicate that the drivetrain and underbody components are nearing the end of their service life. Structural integrity should be verified in person due to the 2024 advisory regarding corrosion on underbody and suspension components. The history of worn suspension arm ball joints in 2023 and track rod end play in 2021 suggests that the steering and suspension geometry may be compromised. Given the high mileage and the nature of the recent failures, a comprehensive check of the chassis for significant rust and the entire braking circuit is necessary. buying_score: 35 risk_level: High.
