Should I check the MOT history before buying a 2018 Citroen C4 Cactus?

The 2018 Citroën C4 Cactus passes its first MOT about 4 percentage points above the UK average at 84.2%, which is a solid result—but nearly a quarter of this cohort (22.2%) have recorded a dangerous defect at some point, which is a genuine concern for a used buyer. Petrol and diesel variants perform similarly, both hovering around 84%, so fuel choice won't be a decisive factor here.

These cars are running at 36,678 miles on average, which is reasonable for a six-year-old model, and the typical owner faces just 1.11 failures per test alongside 6.7 advisory items. The advisory count suggests minor wear accumulates steadily, so budget for small repairs as the car ages—but before buying, specifically ask the seller for full MOT history and whether any dangerous defects were recorded and remedied.

The 2018 Citroen C4 Cactus passes its MOT first time at roughly the UK average rate (84.2%) — solid but worth checking this vehicle's history carefully.

⚠️ 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 6.7 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 5,330 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.
