No, you shouldn't. Diesels aren't designed to be used for less than 12,000 miles per year at a minimum. We generally suggest a driver needs to be doing 15,000 miles per year, with longer journeys being the majority. By longer journeys, we mean more than 15 miles at a time - but higher speed roads are ideal. The feedback we get from low-mileage diesel drivers is overwhelmingly negative. Lots of DPF and EGR problems, all caused by the fact the vehicle seldom reaches its optimum operating temperature. I would advise buying a petrol, hybrid or perhaps electric vehicle.
