2013 Citroen C1 1.0L Petrol · ML63 AAV

The vehicle presents a worsening trend regarding corrosion, particularly within the rear suspension and braking systems. While the most recent test on 10 November 2025 at 86,071 miles resulted in a pass, the tester identified multiple areas of concern including a corroded rear axle, corroded rear suspension spring mountings, and corrosion on both nearside and offside rear brake pipes. This pattern of degradation has been escalating since at least 2021, when the record first flagged corroded front coil springs and brake pipe issues. The mileage accumulation is consistent with a vehicle of this age, averaging approximately 6,600 miles per year. The records show steady usage, with the distance increasing from 42,225 miles in October 2016 to the current 86,071 miles. There are no significant gaps in the testing history, suggesting the vehicle has been in regular use and subject to annual inspections. The progression from 58,466 miles in 2021 to 86,071 miles in 2025 demonstrates a predictable and stable driving pattern. A prospective buyer must conduct a thorough physical inspection of the vehicle's underside, specifically focusing on the structural integrity of the subframes and suspension mountings. The 2024 test at 76,266 miles flagged corrosion on both the front and rear subframes, and the 2025 test confirmed ongoing corrosion on the rear axle and spring mountings. While these were noted as not being seriously weakened, the recurring nature of these advisories suggests that oxidation is progressing. It is vital to check if the grease covering the brake pipes is masking deeper decay or if the pipes require replacement to prevent future failure. The braking system and tyres also require close scrutiny. The history shows a pattern of neglected consumables, such as the 2021 failure for thin brake pads and the 2019 failure for tyre damage. Although recent tests show no immediate failures for these items, the recurring issues with brake pipe corrosion and previous brake fluctuations indicate that the hydraulic system and rear braking components should be checked for leaks or binding. Ensuring the suspension bushes and coil springs are free from excessive surface rust and structural compromise is essential before purchase.
