Should I check the MOT history before buying a 2018 Toyota Yaris?

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 2018 Toyota Yaris?

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 2018 Toyota Yaris?

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 2018 Toyota Yaris is a genuinely reliable car, with an 88.5% first-time pass rate that sits well above the UK average of 80%. Only 11.9% of vehicles have ever recorded a dangerous defect, which is reassuringly low and suggests structural safety isn't a concern for this cohort.

At 27,236 miles median mileage, these cars have been used gently for their age, and the 0.68 average failures per vehicle confirms they're holding up well. Petrol models edge out hybrids slightly (89.3% versus 87.9% pass rates), but both are solid; focus your used car search on full service history rather than fuel type, and you'll have a dependable small car that won't ambush you with repair bills.

The 2018 Toyota Yaris passes its MOT first time more often than most UK vehicles (89.7% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ 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

✅ Good baseline reliability. A 89.7% 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 4.1 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 28,340 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.
