Should I check the MOT history before buying a 2021 Citroen Relay 35 L3 Bluehdi S/s?

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 L3 Bluehdi S/s?

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 L3 Bluehdi S/s?

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 207 vehicles, the 2021 Citroen Relay 35 L3 Bluehdi S/s has a first-time MOT pass rate of 81.4%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2021 Citroen Relay 35 L3 Bluehdi S/s?

The 2021 Citroën Relay 35 L3 BlueHDi matches the UK average with an 80.2% first-time pass rate, and dangerous defects are relatively rare at 13%, making this a reasonably safe bet for a commercial van of this age and size. These are proper work vehicles with modest mileage for their age (average 59,443 miles), which bodes well for durability in the field.

Most owners can expect to fix less than one fault per MOT cycle (0.61 failures), but advisories are common at 2.2 per vehicle—mainly wear items and non-urgent maintenance that come with a working van. Before buying, get a pre-purchase inspection focused on suspension and brake wear, since these accumulated advisories suggest the vans are being put to proper use rather than sitting idle.
