BMW for 17 year old..?

I'm considering getting a 2006 BMW 325i AWD. I've looked at previous posts on Y!A regarding cars for us 17 year olds & all I see is stuff like how your first car shouldn't be as expensive (I agree with that) and also how a teenager with a BMW is rich & spoiled (no).

I used a 2002 Honda Odyssey minivan when I was 16 which was my mom's, and shortly before I turned 17 my dad allowed me to use his 2004 Acura MDX, which is what I use now. (and have been using for nearly a year). My dad has agreed to buy me either a 2013 Subaru BRZ, a 2013 Subaru Impreza or a 2006 BMW 325i. First off, BRZ has practically non existent rear seats. Second, I don'r want him to shell out cash for a brand new Impreza. Third, as I do realize BMWs are expensive, it's obviously a used & I'm getting it for $12,000 (more than half of the brand new Impreza).

I realize there's the whole maintenance issue but that won't be that big of a problem, and the reason I like the 325i is because it drives smoothly & it's a nice car to drive.

and no, I will not be racing, drinking, smoking, etc. while driving although I do understand why most people stereotype teenagers to be the worst drivers, I've seen a lot of teens do this.

My question is, do you think my choice of driving a BMW is wise?

and no, I'm not gonna get a car older than 2005-2006.

and yes, I need a car because I'll be moving out & living on res for university so I cannot continue using the family spare car (2004 Acura MDX)
