Should I check the MOT history before buying a 2021 Citroen C3 Aircross C Series Ptech S/s?

Moderate sample. 474 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2021 Citroën C3 Aircross is a strong performer, with a 94% first-time MOT pass rate well above the UK average of 80%, suggesting owners have fewer unexpected repairs to budget for. Only 8% have ever recorded a dangerous defect, which is reassuringly low and indicates the model hasn't developed common safety issues.

At 23,000 miles median, these are low-mileage examples for their age, so you're looking at cars that haven't been thrashed. The average vehicle picks up just 0.2 failures and 1.9 advisories per test, which is typical wear—when you inspect one, focus your pre-purchase checks on suspension and brake condition rather than electrical gremlins or engine faults.

The 2021 Citroen C3 Aircross C Series Ptech S/s passes its MOT first time more often than most UK vehicles (94.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 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 94.3% 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 1.9 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 474 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.
