Is the 2021 Doblo getting worse?

Test year	Pass rate
2024	75.4% -15.2 vs same-age
2025	76.1% -14.1 vs same-age

FAQs

Is a 2021 Fiat Doblo reliable?

2021-registered examples passed 75.8% of their MOT tests (1,633 tests, 2023–2025), -14.7 points versus all UK cars registered in the same year. At roughly 5 years old with a median 49,260 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2021 Doblo?

The median tested example shows 49,260 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.
