According to the AA, the total costs of running a petrol or diesel car are around £115 per week (60p per mile) for a car costing £13,000 to £20,000 new (assuming average annual mileage of 10,000 miles). The size of this figure often comes as a surprise, as most motorists only consider fuel costs when it comes to calculating the cost of running a car – the true cost also includes depreciation, insurance, road tax, servicing, parts, parking and tolls.
