 I have the 2014 xDrive28i model.  The seats are cheap and not comfortable for a long drive.  The acceleration is more like a Ford Escort than a BMW.  The sales guy said it is because it is a 4 cylinder.  No excuse.  The BMW engineers should be ashamed of what they created.  The navigation is ok, but feels more like my 2004 Infiniti G35 than a 2014.  The steering and suspension are stiff.  This is good for me.  It's very loud on the road.  You hear everything.  The tires wear down very quickly.  The dealer was telling me to replace them at around 13,000 miles.  Ridiculous.  Anyone, besides my kids, who gets into the car has a little trouble, no matter how I position the passenger seat. I've taken the car to the dealer a dozen times over the past 2 years for different problems (wiper blades not contacting windshield, bluetooth wouldn't connect, valve cover leaking oil onto intake manifold, and the list goes on).  Thankfully, I only have one year left on my lease.  It kills me to have to drive this car for that long, but it's the commitment/mistake I made.  I feel like I got taken by the BMW logo.  Won't happen again.
