Should I check the MOT history before buying a 2021 Citroen C4?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2021 Citroen C4?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2021 Citroen C4?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2021 Citroën C4 is a solid performer, passing its MOT first time in 89.4% of cases — well above the UK average of 80%. With only 4.9% of vehicles ever showing a dangerous defect, it's a safe bet from a structural or critical systems perspective.

At 25,732 miles average, these cars are still relatively young and lightly used, which explains the low failure rate of 0.3 per vehicle. The 1.7 advisories per car suggest minor wear items are starting to appear, but nothing alarming; when shopping, get a pre-purchase inspection to check suspension and fluid condition, as these typically make up the advisory list on this generation.
