Why the fuel type changes the number
Diesels carry DPFs, EGR valves and stricter smoke limits, so emissions and exhaust faults account for failures petrol cars never see.
On the Smart (Mcc) Fortwo Cabriolet specifically, petrol is the strongest at 73.4%, and this diesel version sits 2 points below the 73.2% model average.
What it means if you are buying one
The diesel Smart (Mcc) Fortwo Cabriolet fails more often than the model average, so budget for the items that catch this fuel type and treat a fresh MOT as worth paying for. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel Smart (Mcc) Fortwo Cabriolet had covered 72,956 miles at test, against 63,820 for the petrol. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.
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.
