2011 Citroen C1 1.0L Petrol · KP11 ERY

The 2011 C1 passed its most recent MOT on 2025-11-05 at 115,133 miles, though the maintenance trend indicates worsening structural deterioration rather than simple consumable wear. The tester flagged active corrosion on the rear sub-frame and a corroded rear brake pipe covered in grease. Front suspension arm pins and bushes also wore to the point of flagging. These defects suggest the previous owner deferred underbody maintenance. Tyre wear remains a recurring issue, but the structural rust poses a greater long-term risk to the vehicle's integrity. Accumulating 115,133 miles over fifteen years equates to roughly 7,676 miles annually, a typical figure for a city runabout. The record shows a steady progression from 99,383 miles in September 2022 to 115,133 miles in November 2025. No glaring gaps in testing frequency appear, and the mileage accumulation remains consistent. The previous owner used the car regularly, yet the MOT history implies they neglected routine underbody protection despite this consistent mileage. A buyer must inspect the rear sub-frame and brake lines closely. The November 2025 test noted rear sub-frame corrosion and a contaminated, corroded rear brake pipe. These conditions accelerate rapidly if left unaddressed. The nearside rear brake required attention in October 2023, indicating a persistent issue with that specific caliper or circuit. Suspension bushes and pins at the front also degraded between 2022 and 2025. Check the inner rim of the nearside front wheel for distortion, a defect that causes uneven tyre wear. Replacing tyres and addressing suspension play will resolve the minor issues, but the structural rust demands a thorough professional underbody inspection before purchase.
