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 Smart (Mcc) Fortwo Cabriolet specifically, petrol is the strongest at 73.4%, and this petrol version sits 0.2 points above the 73.2% 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 Smart (Mcc) Fortwo Cabriolet had covered 63,820 miles at test, against 72,956 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 Smart (Mcc) Fortwo Cabriolet page separate age from fuel if you want to isolate one.
