Damn, you guys don't drive your cars!
I got my '13 135i in July 2014. It had about 3300-3400 miles on it. It has over 25K now. Of course, it doesn't help that my commute (4days/week) is 75 miles/day.
Then again, we need more of you guys out there! Do me a favor? Go buy an M2 and don't drive that also. I'll be ready for it in a few years...
