Should I check the MOT history before buying a 2018 Citroen C3?

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 2018 Citroen C3?

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 2018 Citroen C3?

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 2018 Citroën C3 passes its MOT first time at 86.8%, a solid 6.8 points above the UK average, with petrol versions performing slightly better at 87.1% than their diesel counterparts at 84.8%. Nearly one in five of these cars (18.9%) has recorded a dangerous defect at some point, which is worth noting if you're buying used—a higher proportion than many competitors in this class.

At around 32,000 miles on the median, these cars show reasonable maintenance; the 5.7 average advisories per vehicle and 0.8 failures suggest minor wear items crop up regularly rather than major faults. If you're considering a used C3, get a pre-purchase inspection done to check brake condition and suspension components, as these tend to be the typical advisory items on this model.

The 2018 Citroen C3 passes its MOT first time at roughly the UK average rate (87.9%) — solid but worth checking this vehicle's history carefully.

⚠️ Around 1 in 8 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 87.9% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 5.7 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 16,150 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
