Jim, if you have no credit, and your parents have good credit, the best thing to do would be to get them to cosign on the car for you. If they are accepting of this car you are wanting to get, and about how seriously you are wanting to get it, they should have no problem cosigning for you. Also, you need to expect to pay probably around 200 a month for insurance for this car. This is an estimate of course, so for 6 months you are looking at $1,200. If you are purchasing a car that is $20,000 your payments will most likely be around $350-400 a month. Just try to make sure you get a good interest rate, and if your parents have good credit, this should be no problem. I wouldn't advise taking out a loan by yourself, but if you think that's the best idea, have at it. If I were you, I would hold off until you have about 1-2k saved up. If you should happen to lose your job for any reason, bills can pile up, and being in college, can really have a great affect on your life. And btw, books for college cost around 5-600$ a semester. I am a med student at the UGA, so I know! I would advise you to look through all your options. To sum it up...

-Have your parents cosign
-Look around and get the best interest rate possible
-Have a little money put back incase something happens
-Enjoy the car
