Citroen C1 Sense (2021)
2021 Citroen C1 Sense
CarHunch analysed 421 real MOT records for the 2021 Citroen C1 Sense. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Citroën C1 Sense is genuinely reliable at first MOT, with a 94.8% pass rate that sits well above the UK average of 80%—and only 5.5% of vehicles have ever recorded a dangerous defect, which is reassuringly low. At just 16,071 miles median mileage for vehicles now three years old, these cars are running light, and the minimal failure rate of 0.16 per vehicle shows owners aren't encountering serious mechanical issues yet.
What this tells you is that the C1 is holding up well as a budget city car should, with advisories averaging 1.3 per test mostly pointing to minor wear rather than structural problems. If you're buying used, check the service history and grab a pre-purchase inspection regardless—but mechanically, this cohort inspires confidence.
What to check before buying a 2021 Citroen C1 Sense
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
