0% is, in a way, free money. I don't like to take out more lines of credit than necessary but when you get 0% interest, you'd be foolish to pay for the car in cash. I'd easily finance $25K (average selling price of the ST) and invest the $25K. You can realistically get 15% return each year on that investment. Plus, if you decide to buy a home at a future time, then just cash out your investment, pay off the car and be done. You'll come out ahead. Talk to your financial adviser. They'll even tell you to mortgage a home even if you're a millionaire and can easily pay cash for the property. They key is to hold onto as much of your own money and long as you can and invest it so you earn interest on it.
