Although most car buyers have few options when it comes to payment offers, some lucky individuals have a choice between taking a rebate and 0 financings. Both options are attractive and most individuals will go a full length to get one of them, but when you qualify for both, you have to decide on which is the best. They work differently with the 0 percent financing reducing your cost by eliminating the interest while the rebate option reduces your cost by discounting the cost of the car. You should use an auto loan calculator to determine the option that gives you greater savings. On most occasions, rebates tend to offer greater value than 0 percent financing, but that varies among different scenarios. Comparing the cost of your lease when rebate and 0 percent financing are factored in will help you find the best option.
