Everybody knows that the purchase price is just one part of the cost of running a car. Other expenses, including depreciation, servicing, parts and fuel, need to be factored in when deciding if your budget will stretch to that shiny new car in the showroom.
That's where Cap HPI's 'cost-per-mile' study comes in. By considering the cost of fuel, depreciation, road tax and service and maintenance, we're able to produce a list of the top 25 cheapest to run cars in the UK. In all cases, the image used isn't necessarily reflective of the specification.
