No money down cars aren’t always crack up to what they are. You can get caught in a car loan that’s upside down on a car loan. But if you have the credit score for a no money down car loan the car dealers with 0 down might be able to work with you for a lower rate auto loan.
What car dealers with bad credit auto loans look at and want to see is an increased credit score and that your payment history isn’t out of wack for future car payments.
You usually need a credit score of 700 or better for a no money down car loan but its never a good idea to not have some kind of car down payment. $100 would even help with a down payment on a new or used car regardless of credit score.
