2010 BMW X5 SUV xDrive30i 4dr SUV AWD (3.0L 6cyl 6A)
Needs better quality & reliability
 The X3 and X5 have the same 3.0 sized engine. But the X5 is about 1000lbs heavier.  Where is the "Efficient Dynamics"?  It is sluggish after making turns.  You are constantly downing shifting gears just to be normal on the roads.  This one is not part of the Ultimate Driving machine class!!
