X3 driver 
2016 BMW X3 Diesel xDrive28d 4dr SUV AWD (2.0L 4cyl Turbodiesel 8A)
Off to a great start
 I have a little over 600 miles on my 2016 X3 xdrive28d.  So far, I'm very happy with the vehicle.  I spend about 2 hours a day commuting and the X3 is a great place to be.  The 2L turbodiesel is not for racing, but it's plenty quick and accelerates to 70 mph effortlessly.  The computer is pretty accurate and mpgs are climbing, currently at 34 mpgs.  After adjusting the seats I find them very comfortable (Nevada leather).  The interior design is classy, although some of the buttons are difficult to see from the driver's seat.  The engine is not as quiet as my Q5 TDI, but you don't hear it cruising down the highway.  The car came with 18 inch wheels with Pirelli P7s and they are quiet so far.  The idrive infotainment system is complex, but most functions work by voice command and it works well.  The build quality is excellent and there are no rattles, even from the panoramic sunroof.  The suspension is firm, well composed and comfortable.  The auto Stop/Start works well and definitely saves fuel at those long traffic lights.  I do disable Start/Stop in sections where I know the stops will be brief.  I can't comment on reliability this early on.  I always look forward to driving this car.
