Should I check the MOT history before buying a 2018 Seat Arona?

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.

The 2018 SEAT ARONA passes its MOT first time at 86.8%, which is a solid 6.8 points above the UK average, but nearly a quarter of these vehicles (23.9%) have recorded a dangerous defect at some point—a genuine concern for any buyer. Petrol versions hold a slight reliability edge over diesel, with pass rates of 87.4% versus 84.8% respectively.

Before purchase, ask the seller for a full MOT history and specifically check whether any dangerous defects were recorded and properly remedied, as that 23.9% figure is worth taking seriously.

For context

✅ Good baseline reliability. A 87.4% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 5.7 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 12,034 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.
