Audi RS5

You won’t be entering into Audi RS5 ownership thinking you’ll be able to cope on a shoestring, and it’s just as well. This is not a cheap car to buy, although importantly, it does cost a very similar amount to the BMW M4 and quite a lot less than the Mercedes-AMG C63. Bills for insurance and tyres will also add plenty to your long-term outlay, and the high CO2 emissions mean the taxman will also claim a fair slice. Fuel bills will also be steep, especially if you use your car in the manner its maker intended, but it’s no thirstier than its rivals according to official figures. Resale values are middle-of-the-road for the class – not quite as strong as the BMW’s, but considerably stronger than the Merc’s.
