Why pick a diesel car?
Diesel cars tend to be more expensive to buy than petrol cars but this is off-set by their lower running costs. With higher MPG figures and lower CO2 emissions, diesel models will go further between fuel stops and cost less to tax compared with comparative petrol cars. For many buyers, running a car is one of their biggest drains on their monthly budget and it is the diesel engine's efficiency that has seen it become increasingly popular over recent years. With lower regular outgoings, a diesel car will make back its increased purchase price quickly.
