Petrol against the other Fiat 500c versions

Why the fuel type changes the number

Petrol cars avoid the DPF and emissions failures that catch diesels, and usually fail on the same consumables as any other car.

On the Fiat 500c specifically, petrol is the strongest at 71%, and this petrol version sits 0.2 points above the 70.8% model average.

What it means if you are buying one

There is little to choose between fuel types on this model, so decide on running costs and mileage rather than MOT record. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.

Mileage is part of the answer

The average petrol Fiat 500c had covered 55,598 miles at test, against 77,004 for the diesel. That is around average, so condition and service history will tell you more than the odometer does.

Fuel type and mileage are tangled together: diesels are usually bought by higher-mileage drivers, so some of any gap between fuels is the miles rather than the engine. The per-year figures on the Fiat 500c page separate age from fuel if you want to isolate one.
