When you want or need to buy a new car, you will need to have a down payment in order to get a car loan at a reasonable interest rate. You could of course “borrow” the money from your credit card, but at 20+%, how is that getting you ahead? Zero percent financing is reserved for great customers, so a car loan is bound to cost you something—and it could be a lot. The best thing you can do is save up as large a down payment as you can afford, and then consider your options. Maybe buying a quality used car rather than a new one will be what it takes to get you the vehicle you want.
