I want to buy my first car but I have a limited budget?

I got my license about 8 months ago and have been begging my parents for a car ever since. My parents have a strong belief that teenagers should be responsible for buying their own first car and that handing a car to a teenager is an accident waiting to happen. Therefore, I have to use all my money if I ever want to buy a used car in the near future. Is there anyplace where cars are cheaper? I've tried looking on websites such as eBay and Craigslist but I am concerned about the reliability of the cars sold. I'm happy with any type of car but I prefer reliable and safe cars such as Hondas, Toyotas and Subarus. Any suggestions for a cheap and reliable source to buy used cars?
