    My First Car

Unless you can pay cash for a car, the decision relies on how much you can afford to pay each month and how much you can afford to pay overall for a car. If you borrow the money, the amount you pay each month and the amount you pay overall for the car depends on how much you borrow, for how long, at what interest rate, and if you decide to buy new or used.

    Below are a set of exercises that will help you make good economic decisions when deciding how to spend your money to purchase a car. Click on the
