ALL ABOUT THE CAR I AM TO SAVE UP FOR"

I am getting a 1999 BMW 328I 4dr sedan. The drive is rear wheel drive. It costs $15,000.000. It comes with a Harden/Karden Music System and a trunk mounted 6 disc cd changer. I am buying it from Jason Wang's place. The place is called Phili Auto Sales in Fremont,CA. It is a 2nd hand car. I will save up all of my New Year's Day money and my paychecks that I get from work when I go to school. It will take me 3-6 years to save $ 15,000.00. I feel happy and excited today and everyday. Is it a good car to own someday? This is my dream car. Please comment on it. Please tell me what you guys think
