Should I get a car loan? Help!?

I'm a college student who needs a dependable car. The one I have right now I've had for 2 years and it's seeing it's final days. I'm always limited on what car I am able to buy because of the money I have saved (around $3,000) is not enough to buy a decent car with mileage under 100k. I have a job, so I imagine making the payments wouldn't be an issue.I have no credit, but I will have a co-signer. Can someone tell me a little more about the car loan process? Thanks!
