The 2026 C3 in petrol/manual guise will typically use the small 1.2‑litre 3‑cylinder PureTech family (turbocharged) paired with a 5- or 6‑speed manual — a light, economical setup but with the characteristic 3‑cylinder buzz at higher revs. As a brand-new small hatch, check the spec level (safety kit and infotainment options are often optional) and expect modest boot space compared with larger family cars; clutch replacement on a manual C3 is straightforward but can be a notable cost if abused.

• Clutch bite and pedal free-play — check for slipping or late engagement during a brisk pull-away.
• Gearshift smoothness and synchros — make sure all gears slot cleanly, especially 1st and reverse.
• Engine vibration and idle quality — a 3‑cylinder petrol should be smooth for the class but excessive vibration can indicate mount or calibration issues.
• Infotainment, Apple CarPlay/Android Auto pairing and rear camera (if fitted) — modern C3s have options that may be missing depending on trim.
• Panel gaps, paint finish and door seals — inspect for delivery/build defects and stone chips on the front bumper.
