I am a performance driven customer and it's the best performing vehicle I've ever driven. Which is not saying much for a former Integra and Civic Si owner, but I enjoy every minute of every drive, especially spirited driving. I have had the car for a little over a year (9K) and have had an oil sensor glitch and a rear lamp failure, which was covered by the warranty. BMW touts free 4-year maintenance, which says an oil change every 15K, that seems crazy to me, so I recommend servicing the car at least once between the free ones. The AWD felt very stable in the typically mild north VA snowstorms.
Navigation with real-time traffic. AWD. Bluetooth. BMW-Assist.
iDrive for MP3 CD playback could use more options. Voice commands are hit or miss. Navigation is missing a lot features available on portable GPS units. I hope BMW has the ability to upgrade the software.
