2012 Citroen C1 1.0L Petrol · SL12 HXN

The C1 presents a mixed but broadly stable maintenance picture as of its most recent MOT on 10 April 2026 at 125,623 miles, where it passed. However, this pass came with a notable cluster of advisories that signal the car is entering a phase where age-related deterioration is accelerating rather than resolving. The front sub-frame remains corroded, a recurring observation dating back to at least January 2023, and has been undersealed as a remedial measure. Both front wheel bearings now show slight play, front suspension arm rear bushes are worn on both sides, and both front tyres are worn close to the legal limit. A minor rear exhaust leak, a coolant leak, and a non-excessive oil leak round out the list of concerns. None of these individually constitute a failure, but together they suggest the car has been kept running rather than proactively refreshed. The mileage progression tells a story of consistent, moderate use. From 101,054 miles in January 2023 to 102,151 miles in January 2024, the car covered just over 1,000 miles in twelve months. That figure then jumped to 103,339 miles by February 2025, a gain of roughly 1,188 miles in thirteen months. The most striking leap occurred between February 2025 and April 2026, when the odometer moved from 103,339 to 125,623 miles, an increase of 22,284 miles in just over fourteen months. That equates to approximately 18,800 miles per year, well above the car's lifetime average of roughly 8,973 miles per year. The MOT record alone cannot explain this sudden acceleration, but it does mean the mechanical components flagged in the most recent test have been subjected to significantly higher wear rates in a compressed timeframe. The February 2025 failure at 103,338 miles is a critical data point. Excessive corrosion was identified on both rear suspension component mounting prescribed areas, with structural strength described as significantly reduced, and the nearside rear seat belt anchorage on the outer sill showed the same severity of corrosion. The car passed five days later at 103,339 miles, implying repairs were carried out immediately. A buyer should inspect the rear sills, seat belt anchor points, and rear suspension mounting areas in person, checking for the quality of any welding or plating work and looking for signs of fresh corrosion returning. The front sub-frame, which has been flagged as corroded on every test from January 2024 onward, warrants close examination with a torch and probe. Surface treatment may be masking deeper section loss. Brake system integrity also demands attention. Corrosion on brake pipes has appeared repeatedly, including a February 2025 advisory noting a pipe corroded and covered in grease or other material, suggesting a history of patching rather than replacement. The front brake discs were flagged as worn, pitted, or scored in January 2024, and the nearside rear service brake was binding at that test. With the mileage surge since early 2025, a fresh inspection of disc thickness, pad condition, pipe integrity, and caliper operation is essential. The worn front suspension bushes and wheel bearings, combined with the recent tyre wear advisories, point to a front end that has absorbed considerable punishment. Have the bushes, bearings, and tyres assessed on a ramp, and budget for replacement if original components are still in place.
