Compare cars and make smarter decisions

Compare ownership costs, finance options and running costs with simple guides and tools.

Running a car is one of the biggest ongoing costs for most UK households, and the right choice depends on far more than the purchase price. Fuel, insurance, road tax, servicing and depreciation all add up, and they vary widely between petrol, diesel, hybrid and electric cars.

Our car comparisons and calculators help you weigh up the real cost of each option for your own mileage and circumstances, from electric versus petrol to PCP versus HP finance, so you can decide with the numbers in front of you rather than a salesperson's pitch.
