I suppose I can say a few words about this. I usually don't get into discussions like this but I feel I have a good perspective on this one. I will have to agree with everything NoBoundaries said on the topic. It was well said.
Now I am not far ahead of you, and being only 21, I still have MUCH to learn. I read threads like these and take what the more experienced adults here have to say very seriously. They have been through it, and believe it or not, they have learned things, and know just a little more about life and money than you do at this point.
Now, being a little closer to your age than they may be, lemme try to help shed some light. When I was in high school, I wanted a really cool truck too. I went to a private school, and many of the kids there had parents with money, so some of those kids got some really nice rides. Well, I had a 1987 Ranger and I was jealous, but I had a job and my parents wanted me to save my money. They bought and paid for the Ranger, and the insurance, and almost all my gas, (and I was damn grateful). They also bought my 95 Explorer for me, which I am now in the process of paying off. It wasn't until I got to college, where I chose a difficult major which left little time for a side job, when I realized how lucky I was that my parents encouraged me to save. Man, that little cushion of cash was nice to have when I wanted to do something, or needed something. I don't know what I would have done if I had a truck note.
And lemme tell you something else, college may seem a long way off now, but you had better work your butt off in high school and make good grades if you want to go to a good college. I sure wish I had worked harder. All colleges see is a Grade Point Average and an ACT/SAT score. They don't know or even care how hard you worked to get the GPA or test scores. They judge you by a number. And college isn't any easier, only this time, it's for real. I'm in the middle of it now...companies looking to hire see a number (GPA). Although they do look at other accomplishments you've made during your college years some, but to get that first interview, an impressive GPA is a big help.
Bottom line...follow these guys advice. Get an older, less expensive vehicle, keep your grades up in high school by studying...not working 40 hrs a week to pay for your wheels. You'll have the rest of your life to be in debt. And after you get that nice high paying job after working hard through high school and college, go buy your 2006 Sport Trac. They'll probably be cooler looking then anyway.
