Should I check the MOT history before buying a 2004 Mazda Bongo?

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.

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.

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.

Moderate sample. 442 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2004 Mazda Bongo's 77.4% pass rate sits slightly below the UK average of 80%, which is a minor concern—but the real red flag is that 27.8% of these vehicles have recorded a dangerous defect at some point, nearly 40% higher than you'd expect for a 20-year-old van. This suggests structural or safety issues are worth investigating closely before purchase.

At 111,500 miles average, these Bongos have genuinely high mileage for their age, which partly explains the 2.91 failures per vehicle and especially the 13.6 advisories per vehicle—wear and tear accumulates fast on a van this old. Before buying, get a pre-purchase inspection that specifically covers the suspension, brakes, and bodywork for corrosion, since advisories cluster around these areas on aging campervans.

The 2004 Mazda Bongo has a decent first-time pass rate (77.4%), 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 13.6 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 442 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.
