Buying a Car

I am trying to buy my own car. My parents have graciously allowed me to use their's throughout college, but I will graduating soon and will be needing to buy one of my own. I have been working to earn and save money for the passed year, but I can only work so much as a full time student. In addition, much of that saved money will be going back to repay my parents for the tuition that has been higher than anticipated. Any help you can provided in assisting me get on my feet in 'the real world' will be much appreciated. I would like to raise enough to buy a decent car that would not require further maintenance or replacing in the upcoming couple of years. Thank you very much for your consideration.
