You spent some amount of money on the car, money that you would otherwise have available to either spend or invest, when you eventually replace your car you will get less if anything. So even if the car just sits in your garage you are paying for it (or really already have)
this might be less than you would be paying for renting a car (or more! depending on how often you'd need to rent), but it's obviously not 0
