I don't know where to put this, so I guess it fits best here. I turn 17 in about a week. In the beginning of the summer, I got a job and didn't know what I was going to spend my money on. I then decided that I wanted to buy a car for myself. I told my parents and at first they laughed at me, but then said I can buy it when I have the money, but I'll have to pay for insurance. I'm fine with that. So all Summer, I get really excited because I'll finally have my own car. I finally get enough money and find a car and tell my parents and they refuse to let me buy it. They say that I can use my sister's car when she is at college and that I would be wasting my money if I buy a car. They said that I go to college after this year so it would be a waste since I'm not allowed to bring the car with me. I ask them why did you say I could buy it in the first place. They said they should have never said that. But its too late for that, they did tell me I could buy it, they can't just change their mind like that. I keep asking them that what am I going to do when she comes home for vacation? She comes home for a month for Xmas, like 3 months for summer, plus all the other small vacations that she would come home for. It's her car so she gets to use it when shes home so I'll be out of luck and there are no other cars to use. My parents keep saying we can work it out, but that won't work. When shes not at school, she works 5 days a week, 9AM to 6PM and goes out on the weekends. I'll be stuck in the house all day. I keep telling my parents that and they said it will work out, but I know it won't. They say I can buy one in a few years, but how do I know all this won't happen again when the time comes? I need a car NOW anyways. They each saved up their money and bought a car when they were teenagers, so why can't I? They said I could buy one, and now they change their mind like that, and it ruins everything I've been looking foward to. What could I say to them to convince them to let me buy a car. It is complete bull shit.
