Is the 2020 Doblo getting worse?

Pass rate of 2020-registered cars across recent test years:

Test year	Pass rate
2023	81.3% -9.6 vs same-age
2024	80.2% -9.7 vs same-age
2025	73.2% -15.7 vs same-age

The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

FAQs

Is a 2020 Fiat Doblo reliable?

2020-registered examples passed 78.2% of their MOT tests (2,250 tests, 2023–2025), -11.7 points versus all UK cars registered in the same year. At roughly 6 years old with a median 31,352 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2020 Doblo?

The median tested example shows 31,352 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.
