2007 Citroen C2 1.4L Diesel · NA07 ACU

The most recent MOT in February 2022 resulted in a pass after an initial failure two days prior, with the major defect being excessive corrosion to the nearside rear suspension mounting area, which was presumably addressed. However, the broader history reveals a worsening trend in structural integrity, particularly with recurring corrosion-related failures affecting the sills, sub-frame, and seatbelt anchorages, alongside persistent advisories for underbody and sub-frame corrosion. While some mechanical components like suspension bushes and ball joints have been flagged intermittently, the dominant concern is the progressive deterioration of the vehicle’s structural and safety-critical areas, suggesting that long-term reliability may be compromised without significant remedial work. At 19 years old with 109,117 miles, the annual average of approximately 5,743 miles indicates relatively low usage for its age, which may point to prolonged periods of inactivity. This can be as problematic as high mileage, as standing vehicles are prone to seals drying out, brake components seizing, and fluids degrading over time. The low mileage does not offset the age-related wear evident in the MOT history, and the combination of calendar-based deterioration and existing structural corrosion demands close scrutiny. A thorough inspection should prioritise the structural integrity of the sills, sub-frame, and seatbelt anchorages, as these areas have repeatedly failed or been flagged for corrosion. On a test drive, listen for clunks or knocks from the front suspension, which could indicate worn ball joints or bushes, and check for uneven tyre wear or pulling to one side, which may signal alignment or suspension issues. The ABS warning lamp history also warrants verification of the system’s current functionality, as electrical faults can resurface. Additionally, inspect the brake discs for pitting or scoring, and ensure the wheel bearings are quiet, as these have been noted in earlier advisories. Given the vehicle’s age and potential for prolonged standing, pay particular attention to perished rubber components such as tyres, suspension bushes, and coolant hoses, as these degrade over time regardless of mileage. Check the 12V battery health, as low usage can lead to sulphation and reduced capacity, and examine the underbody and exhaust for extensive corrosion, which may not be immediately visible but could affect long-term roadworthiness. Finally, verify the service history to confirm that time-sensitive fluids, such as coolant and brake fluid, have been replaced, as these lose their protective properties over the years.
