MY CARRRRR!

Ok so I have been looking for a car. This is a bad thing for a few reasons. ONE : every car that I see and that I love I get my mind set on it and that's not good. TWO: I have no money to buy a car but I desperately need one soon. THREE: I have some good news. Me and my mom are going to try and compromise. She is thinking about agreeing with me on this one. There are two cars that I really like. One is a 1997 Mitsubishi Eclipse Spyder GTO and its selling for $2,000 and the other one that I LOVE is a 1999 Chrysler Sebring and that's $2,995. Both are convertibles. So she might think about buying me one and I pay her a certain amount of money a month for a certain amount of months. I figured it all out and I explained to her my plain and she said she will think about it....which is a better answer than a no because it may mean she will actually consider it. I also think its a good idea because paying a car payment is a big responsibility and it may help me in the future. I'm also paying for my own insurance, gas, registration, inspection and I paid for my own drivers ed and the licence. So can anyone back me up on this. Do I have a good idea or what? Ive done pretty good on my own so far I think I deserve a car.....?
