Car dealerships sometimes use zero-percent financing offers to attract new car buyers looking for inexpensive credit. The drawback of a 0 percent promotion is that most people don't qualify, according to CarsDirect. This is why auto dealers typically indicate in the fine print of the promotion that buyers must "qualify" to get the deal.

Credit Requirements

Usually, borrowers need at least a 700 credit score to qualify. In fact, a 720 minimum is common in many of the promotions. The good news for those that don't have adequate credit is that you can take advantage of alternative rebate offers and other deals that you can't normally combine with a 0 percent deal. Additionally, the length of a 0 percent loan is normally 24 to 36 months.
