2016 Citroen C3 1.2L Petrol · BV16 AKO

The 1.2-litre PureTech petrol is a relatively economical unit, typically returning mid-40s mpg on a combined cycle, though the higher-than-average mileage on this example suggests real-world economy may be lower if predominantly urban. Road tax sits in a low band for this engine size, and insurance is generally modest thanks to the C3's position in the lower insurance groups.

Maintenance costs are where buyers of older Mk3 C3s need to be realistic. Common wear items — front brake pads, discs, coil springs and tyres — are reasonably priced, but labour at a main dealer can be steep. Annual servicing on a petrol C3 of this age typically runs £200–£350 at an independent specialist. Allowing for the higher-than-average mileage, an annual running cost in the region of £1,200–£1,500 covering fuel, tax, insurance, servicing and consumables is a realistic working figure.

Start with a thorough walkaround checking all four tyres for uneven wear, particularly inner-edge wear on the front pair — this was flagged on both sides in 2025 and may indicate alignment or suspension issues following the fractured spring replacement. Inspect all exterior lamps for operation, including front position lamps and the registration plate illumination, which were defective in 2025. Test the horn, all washers and confirm the engine management light extinguishes promptly on start-up; the MIL was the recurring item in both 2026 tests.

Under the car, look for fresh corrosion on the front suspension, particularly the spring seats and top mounts, and check for any oil seepage from the shock absorbers. On the test drive, listen for clonks over bumps from the front end and check the parking brake holds the car on a slope — both the parking brake efficiency and brake disc condition were noted in 2025. Inside, check that all warning lamps cycle correctly on ignition, and have any persistent MIL code read with a diagnostic tool before purchase.
