Buying a diesel car is far more expensive than buying one running on petrol. In order to win back the surplus you're paying for a diesel engine, you need to drive at least 25,000 kilometres (16,000 miles) per year.
Joni Junes of VAB: "If you cover only few kilometres with your diesel car, costs for maintenance will be soaring. Your diesel particulate filter will not regenerate, to give one example." It's also bad for the environment: "If you often cover short distances in the city, particulate matter emissions will go up."
Still, many Belgians are fond of a diesel car. "It's important to make the right choice when buying a car. People often overestimate the number of kilometres they will drive."
