CCC Problem
 Great car but there is a issue with the CCC aka iDrive.  I had one go out under warranty at about 40,000 and now again it went out at 79,000 but this time I have to pay and it costs $1600 to replace. I have the certified pre- owned warranty which the dealership that I bought from said was bumper to bumper (the salesman lied) and now I have to suffer the consequences. Also the brakes squeal even though they do not need to be replaced.  The rear tires wear fast because in the sports suspension, the wheels are slightly inward on purpose for handling so you will have to change tires frequently. Do not recommend if you don't have a lot of money to pay for service.
