It’s almost always cheaper to buy a car outright in cash rather than financing it. With no interest due, you’ll only be paying the car’s purchase price.
Of course, it’s not always possible to go down this route – and you might not want to.
If you buy a car outright, you’ll have to deal with its depreciation (loss of value over time) and the potential hassle of selling it in the future. Choose a PCP car finance deal or lease instead and you could simply hand the car back.
