2018 Mercedes-Benz SLC: petrol or diesel?

Petrol, diesel and hybrid versions go wrong in different ways, so each has its own figures from the MOTs these cars had during 2023–2025. Pick the one you’re looking at: the fuel is on the logbook and in the car’s MOT history.

Petrol 90% pass first time (all 2018 cars: 83%) Stands out: wheels 2.5× 3,912 MOTsSee the petrol guide › Diesel 84% pass first time (all 2018 cars: 83%) Nothing stands out above the usual rate 511 MOTsSee the diesel guide ›

Hybrid versions had too few MOTs for figures of their own, or weren’t sold.
