Should I check the MOT history before buying a 2020 Fiat 500 Rockstar?

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 2020 Fiat 500 Rockstar?

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 2020 Fiat 500 Rockstar?

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.

Is the 2020 Fiat 500 Rockstar reliable?

Based on MOT data from 685 vehicles, the 2020 Fiat 500 Rockstar has a first-time MOT pass rate of 87.9%, 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 2020 Fiat 500 Rockstar?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

The 2020 FIAT 500 Rockstar is more reliable than average, with an 87.1% first-time MOT pass rate well above the UK average of 80%, suggesting a solid build quality for this generation. However, 16.8% of these vehicles have recorded a dangerous defect at some point, which is worth noting if you're buying a used example—inspect brakes, steering, and suspension carefully.

At just over 26,000 miles median for a four-year-old car, these 500s are lightly used, so you're looking at vehicles with genuine low mileage. The average of 0.57 failures per test and 3.3 advisories per vehicle points to minor wear issues rather than structural problems—typical for a small city car—so budget for routine maintenance but don't expect surprises; get a pre-purchase inspection focused on those dangerous defect categories before committing.

The 2020 Fiat 500 Rockstar passes its MOT first time at roughly the UK average rate (87.9%) — 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 87.9% 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 3.3 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 685 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.
