In 2025, 38,784 Fiat Doblo cars had a regular MOT in Great Britain. 63% passed first time, compared with 69% for all cars of the same ages, which makes the Doblo worse than average. Most are commercial vans or pick-ups, which usually cover far higher mileages and harder work than private cars, so we leave them out of the car rankings.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 4 years old, 71% of Doblos passed first time (all cars that age: 87%). By 20 years, that figure is 50% (all cars: 58%). It is weaker than average when young but holds up better than most from around 12 years.

What to check when buying a used Doblo
Based on where the Doblo fails more often than other cars, these are the checks worth making before you buy:
- Emissions and leaks: Look for oil and coolant leaks underneath, listen for exhaust blows on a cold start, and watch for smoke when revving. Repair guide
- Body and structure: Get underneath with a torch: sills, jacking points, subframe mounts and floor pans. Structural rust is the failure that can make a car uneconomic to fix. Repair guide
- Suspension: Listen for knocks over speed bumps, look for leaking shock absorbers, and check the car sits level. Ask whether springs, bushes or drop links have been replaced. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
