2010 Citroen C1 1.0L Petrol · BN60 ACU

The 998cc petrol C1 is one of the cheapest small cars to run when mechanically sound: real-world fuel economy of around 50–55 mpg is realistic, and insurance typically falls into group 3–4, keeping premiums low. Road tax for a petrol car of this age and engine size is minimal at the current VED rate for vehicles registered before April 2017 that fall below £40,000 list price. Parts are generally inexpensive and shared across the Toyota Aygo and Peugeot 107 sister models, which keeps replacement component costs down.

However, the running costs for this specific car should be viewed in the context of its MOT history. With multiple suspension components, brake discs and possibly exhaust repairs (a minor exhaust leak was noted in 2024) needed in the near term, the first year of ownership is likely to be more expensive than the C1 norm. Realistically, budget £1,000–£1,400 per year covering fuel, tax, insurance, tyres and the maintenance backlog, rather than the £600–£800 you might expect for a tidy example.

Begin with a thorough inspection of the suspension on a ramp: the MOT history flags corrosion on both front and rear shock absorbers, all four coil springs, and perishing bushes on the front lower arm rear positions and rear trailing arms. Tap each spring with a hammer — any cracking or flaking means immediate replacement is required. Lift each front wheel and check for play in the track rod ends (the 2024 and 2025 advisories indicate deteriorated dust covers on both sides, which suggests the joints themselves may be approaching end-of-life).

For the brakes, expect the front discs to need replacement due to the lipping recorded in 2025, and inspect the rear drums for the binding problem seen in 2023. Operate the parking brake lever manually — if it has excessive free travel as flagged in the 2025 failure, the cable adjuster or the shoes themselves need attention. Also check the underbody for the inner sill corrosion mentioned in 2024; while described as not significantly reducing structural rigidity, this is a known weakness on older C1s and warrants a close look. Finally, look for any oil leaks (an 'oil leak, not excessive' was noted in 2025) and confirm the exhaust system for the minor leak flagged in 2024.
