Wanting to buy my first car!!! Help, need some ides!?

[Jake]

I'm 14, turning 15 in May. I just started saving for my first car in advance, because I know that the day will come soon when I need a car! My parents let my sister borrow their 3rd car when she started driving, but she's in college and I'll need one to. I'm sure my parents would figure something out for me, weather they buy themselves a new car and let me use their current car or chipping in on buying me a used car. I will be paying the big chunk for the car though, and they'll probably pay agilest $2,000. Anyway, I already have $1,400 saved up, and I've been saving that over the years, and it's in the bank. I've made up my mind on what kind of car I want and it's a BMW. I want this car because it's a great stylish car, and I will know that I have accomplished something great! It's a personal goal for me to be able to save enough money for a BMW by the time i'm 16-17. I also want to buy my own car because it's about the responsibility factor to. Also i'll be so proud of myself knowing that I saved up for such a nice car. My goal is to save up $7,000 to $8,000, so I can buy a nice 2000 or 2001 BMW. My question is how can I save all this money by then! I want to get a job this summer but once you get in the working world you don't get out, and I'm not sure I could even make enough to save this much up. Im cracking down on myself, and I'm saving everything, so i can buy this car. I have mowed lawns in the past which was good, but with the economy it's not going to fly. I need some creative working ideas/investing plans so I can save this money up! Also give me some creative self Business ideas please! Thankyou!
