How to raise $20,000 Min. before the age of 17-18 (DeLorean)?

Hello, I am here to say this. Once I saw "Back to the Future" when I was 6, I fell in love with the DeLorean. There hasn't been a day that's gone by without my thinking or saying something about that car. Im now about to turn 15 years old and I want that car, BAD. Hell I went to see one at a Lamborghini dealership and the guy didn't even know that some interior parts were from a Volkswagen and its easy to see that! Anyways, I've sold most of my toys and old stuff and im just close enough to make only 1k. Not only that but Im getting a job for summer break, maybe even two (if that's possible) The cheapest Deloreans I can find are for $20,000. I found one at a GM dealership for that price and in almost mint condition inside and out. Besides a radio that gives out 2 years after you install them and some pealed engine stickers, That was the best F**King Delorean I have ever seen. I thought it was fate that I found that car, IT WAS MEANT FOR ME! Even when my dad said it was time to go I locked myself in the car and told him he would have to make me first; Moments later the manager came and told me to step out of the car. I would have just sat there, but I was afraid he would call the cops on me. All this is just part of my story. That is why after bugging my parents for so long the only thing they would say to me is "only if you get the money!" So if I can get $20,000 minimum I can buy me an awesome DeLorean to prove John DeLoreans slogan,"Live The Dream" The dream that the average driver CAN have the same feeling of fancy sports car. THAT is what it means to live the dream. Yes, we know that he screwed up from starting in Belfast to the cocaine trail, but it doesn't mean that the dream is dead; and with retro things coming back, why not! To Live The Dream still has the same meaning; but its not only to feel like your driving a fancy sports car, but to also capture a little but of the past and what they thought what the future should have been. THAT is why this 14 year old wants a Delorean! So when your kid says he wants a car, ask him first if he/she knows the MEANING of that car. So, how can I find the money to bring this dream to reality?
