If you want to know how to save money on a new car purchase, consider the many rebates and incentives typically offered by most major car manufacturers. It's easy to show up to a dealership, pick a car, and use the financing options at the dealership to pay for your new vehicle. Of course, you don't want to pay for anything major when you've only had your car for a few years, but most manufacturer warranties should still have you covered within the first three years of car ownership.
