What to check before buying a 2020 C3 Flair + Puretech S/S

Before buying a 2020 Citroen C3 Flair + Puretech S/S, focus on the areas it most often fails on. Lighting & signalling accounted for 3.8% of tests for this year.

Lighting & signalling (3.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Tyres (2.8% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Brakes (2.2% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
