Due to depreciation, you will likely be upside down on the car loan at some point. So to minimize this, you should attempt to pay more toward your monthly bill each month, round your payments up to the nearest $100, or make principal-only payments. By doing so, you can reduce your overall principal and shorten the length of the loan.
Another advantage of this is that you will reduce how long you have to keep full coverage car insurance on your loan, or at least give you the option of switching to liability. This is because lenders require full coverage car insurance on financed vehicles.
