18 here. My first car was a 2002 X5 4.4i that I got used with about 35000 miles in spring 2004. Then I got a 2003 330xi in January, 2005. I've still got her, she's got almost 124,000 miles.
My parents wanted me driving something safe and reliable, like a Volvo. I wanted something that I'd enjoy driving. Hence, a used BMW was the answer!
