 Build quality was fine; but it is sluggish and slow and has no feel for the road.   It lacks the exciting driving feel you'd expect in a BMW.  The Turbo 4 is inadequate and leaves the car under-powered and wanting.   The navigation system still requires  a lot of patience.  It's not intuitive.    The tires have been a disappointment. They started cupping in front at 20,000 miles.   Unfortunately, the car drives like an under-powered Buick or Ford Taurus rental.   If I'd wanted a Buick I would have bought one for $20,000 less.    Very disappointed.   I've owned six BMW's and this is by far the worst.   Believe the new redesign in '17 is intended to remedy many of the cars faults.   As soon as I can I'm going to dump this dog.
