How can i get money for my first car?

i'll be 15 in november so i want to start saving up to get my first car. neither of my parents are helping to get me one so i'm on my own with this. i'm not looking for a new car but a used one. i want a spyder eclipse but the lowest price i've seen them for is $10,000. but the problem is that i don't have a job and so i have no money coming in. if i can't get the spyder eclipse as my first car, i'll understand b/c of the price. i'm not sure what my second choice would be for a car.. but how can i start getting money in for my first car if i'm not quite old enough for a real job?
