Should I check the MOT history before buying a 2021 Citroen Relay 35 Hvy L4h2 Ent Bhdi Ss?

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 2021 Citroen Relay 35 Hvy L4h2 Ent Bhdi Ss?

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 2021 Citroen Relay 35 Hvy L4h2 Ent Bhdi Ss?

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 2021 Citroën Relay 35 HVY L4H2 falls slightly short of the UK average with a 75.4% first-time pass rate against the national 80%, suggesting reliability is a touch below typical—though the 10.5% dangerous defect rate is manageable and not a serious red flag. Diesel vans in this class often show variable results, so this represents a middling performer rather than a standout.

At nearly 61,000 miles average, these vans are running typical mileage for a three-year-old commercial vehicle. The 0.52 failures and 1.9 advisories per test indicate minor issues dominate over serious failures, but the median Carhunch score of 50 reflects that you're not buying a particularly robust example—budget for remedial work at the next MOT and have any pre-purchase inspected by a diesel specialist familiar with Relay powertrains.

The 2021 Citroen Relay 35 Hvy L4h2 Ent Bhdi Ss passes its MOT first time at roughly the UK average rate (82.1%) — solid but worth checking this vehicle's history carefully.

⚠️ 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

🔧 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 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 1,047 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.
