Sorry for maybe misleading you. I actually bought my car a little over a year ago (sold the E46 M3 to get the E92 M3) and when I was searching, the best value I could find was one at Carmax in Chicago. It was a free transfer down to Indianapolis, so I had the transfer done so I could test drive it. Fell in love and bought it. I was just curious who the previous owner was and why he sold such an awesome car!
I haven't had any problems with it either, so was just curious. The nice thing about Carmax is that I have their warranty which is 6 years or 125K miles. So if something happens outside the BMW warranty, I still feel have the Carmax warranty to save me from costly repairs!
