Should I check the MOT history before buying a 2021 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.

What corrosion should I look for when inspecting a 2021 Citroen Relay?

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?

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.

Based on MOT data from 128 vehicles, the 2021 Citroen Relay has a first-time MOT pass rate of 78.6%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

The 2021 Citroën Relay has a first-time pass rate of 78%, just shy of the UK average of 80%, suggesting broadly typical reliability for a van of this age. Only 10.2% of vehicles have ever recorded a dangerous defect, which is reassuringly low and not a major buyer concern.

At a median mileage of 23,186 miles, these vans have been driven lightly for their age, yet they're still averaging 0.81 failures per vehicle—indicating that wear issues are emerging despite relatively low use. The 1.6 advisories per vehicle suggests routine maintenance items (brakes, lights, wipers) are cropping up regularly, so budget for preventative upkeep and request a pre-purchase inspection covering wear items before committing.

We have limited data for the 2021 Citroen Relay — treat the figures below as indicative rather than definitive.
