Is the 2018 500 getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 87.2% -0.9 vs same-age |
|
| 2024 | 83.8% -2.5 vs same-age |
|
| 2025 | 80.4% -4.3 vs same-age |

FAQs
Is a 2018 Fiat 500 reliable?

What mileage is too high for a 2018 500?
The median tested example shows 30,224 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
