Petrol against the other Mercedes-Benz Clk 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 Mercedes-Benz Clk specifically, petrol is the strongest at 69.6%, and this petrol version sits 1.5 points above the 68.1% model average.

What it means if you are buying one

The petrol Mercedes-Benz Clk is the stronger side of this model on MOT data. Still judge the individual car, but the fuel type is a mild point in its favour. 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 Mercedes-Benz Clk had covered 99,547 miles at test, against 126,956 for the diesel. That is above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust.

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 Mercedes-Benz Clk page separate age from fuel if you want to isolate one.
