Should I check the MOT history before buying a 2018 Fiat 500?

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 Fiat 500?

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 Fiat 500?

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 FIAT 500 passes its MOT first time at 85.9%, which is a solid 5.9 percentage points above the UK average, suggesting good overall reliability for the age. However, nearly 1 in 5 vehicles (18.7%) have recorded a dangerous defect at some point, which is worth factoring into your inspection checklist as a buyer.

These cars are running at a sensible 25,759 miles median for their age, and they average 0.83 failures per test—low enough to suggest they're not chronic problem cars. The high advisory count of 5.9 per vehicle points to minor wear items rather than structural issues, so budget for routine maintenance but don't expect major surprises if you buy one with a clean recent MOT history.

The 2018 Fiat 500 passes its MOT first time at roughly the UK average rate (87.6%) — solid but worth checking this vehicle's history carefully.

⚠️ Around 1 in 8 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 87.6% 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 5.9 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 23,975 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.
