Should I check the MOT history before buying a 2018 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 2018 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.

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 C4 passes its MOT slightly above the UK average at 83.3%, which is respectable, but nearly a third of these cars have recorded a dangerous defect at some point—that's a genuine concern for safety-conscious buyers. Petrol and diesel versions perform similarly (84.2% and 82.9% respectively), so fuel type won't be a deciding factor here.

These cars are showing modest mileage for their age at around 40,000 miles, and while the average of 1.03 failures per test suggests most get through without major issues, the 7.0 advisories per vehicle indicate niggling wear items are common. Before buying, budget for routine repairs and have a pre-purchase inspection focus on brakes, suspension, and electrics—the typical weak spots in this cohort.

The 2018 Citroen C4 has a decent first-time pass rate (84.9%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 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

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 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 2,751 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.
