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

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.

The 2018 Citroën Relay falls slightly below the UK average with a first-time pass rate of 78.9% versus 80%, which is a marginal difference but worth noting. More concerning is that 29.6% of these vans have recorded a dangerous defect at some point, well above the typical threshold—this is a genuine red flag for buyers considering one.

At 68,500 miles median, these Relays show typical mileage for their age, but the average of 1.43 failures per test suggests structural reliability issues beyond normal wear. Check the service history carefully and budget for around 5.8 advisory items per vehicle; focus your pre-purchase inspection on braking components and suspension, which typically dominate the failure list on this model.

The 2018 Citroen Relay has a decent first-time pass rate (79%), 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 5.8 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 6,357 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.
