Don't do it. You don't want to have to live month-to-month wondering if you've got enough to eat or pay for your car insurance. Worst thing you could do is ruin your credit rating early on, or build up a huge credit card debt paying for everything. It's just not worth it. If you want to know what payments are, there are a lot of calculators out there (Yahoo Autos has one) to work it out.
