What to check on a 2018 Citroen C1 before buying
The three areas where failed first tests most often had a fault, 2023–2025.
- Tyres. Worth checking the tread depth across the whole width of each tyre, and the sidewalls for cuts, cracks and bulges.
- Wipers and windscreen. Worth checking that the wipers clear the screen cleanly, that the washers work, and that there are no chips or cracks in the driver’s view.
- Brakes. Worth looking at the discs and pads through the wheel spokes for scoring and a worn lip, and noticing on the test drive whether the car pulls to one side or the pedal feels long.
