Can I buy a car with no money down?

Often yes, if your credit and income are strong enough, and some promotions specifically advertise zero down. The trade-off is a higher loan balance, a higher payment, more interest and a greater chance of being upside down early in the loan, since a new car loses value quickly. If you do put nothing down, consider a shorter term and look into GAP coverage, which can cover the gap between your loan balance and the car's value after a total loss.
