Save money for a car.

Umm I currently have $300, and man was that hard to save. I don’t know how the hell I’m going to save a couple thousand dollars. I’m 15, almost 16, so I don’t have that much time :/ My parents won’t buy me a car because they said I always get what I want and I need to save myself. I guess I kind of agree with them, I do get everything easily and saving for a car will be good for me. So as soon as I turn 16 I’m getting a job, and I should probably open a bank account to earn interest.
