The people who will loan you the money need assurance that you will pay them back or that they can have something of yours (collateral) if you stop paying. In most car loans, the car itself is the collateral. So, if you stop paying on the car, they reposess that shit. It is not quite that simple, but that is the idea behind it.
I assume you are young, don't own anything of major value, don't have a full-time job and don't plan on putting money down on the car. If this is true, ask your parents if they will co-sign for you. That means that they will pay the penalty if you don't make the payments. If I'm wrong on my assumptions, feel free to correct me.
