This car is truly a blast to drive. Fast, nimble, all the cool toys inside- -THe Ultimate Driving Machinge without question. The engine sounds great, feels smooth and never seems to hit the end of the power band. Interestingly, I get 26-27 mpg on the highway and combined of about 20--not much less than my 325. All in all, this is the best 4 door performance car on the market. After driving it, all the complaints about the I-Drive, styling or other small stuff sounds more like sour grapes from those that do not get to drive one to work each day.
The top feature is the 360hp and the bluetooth phone system. While there are many complaints about the I-Drive, it is not hard to use at all. Once things are set, there is very little to change anyways. Lastly the Premium Sound System is spectacular, home theater quality.
BMW has never figured out that we stop at Starbucks in the US and need cup holders. The new ones are simply adequate. Otherwise, no complaints-- very easy car to like.
