There are really only two ways for you to buy a car: Pay cash or take out a loan. If you’re paying cash, budgeting is pretty simple. But don’t spend all your savings. Remember to set aside money for registration and insurance — and possible future repairs. Most people take out a car loan so they can protect their savings and buy a more expensive model. It’s smart to get preapproved for a car loan because it simplifies the buying process and puts you in a stronger position at the car dealership. You’ll see later how preapproval fits into the process.
