 On the negative side: The high end Bose Centerpoint audio system in the Grand Touring is a big disappointment. Overall muddy sound. Distinctly lacking in clear tonality, particularly in the mid-range. Front seat bottom cushions are too short. The turbo 4 cylinder is fine at highway speeds, but it sounds unrefined when accelerating and at lower speeds.  Feels like a cheap engine.  Not enough miles behind the wheel to judge fuel economy, but dipping into the turbo drives down the mpg.   On the positive side: Very good styling. Quality of interior materials is good.  Instrumentation good. Control interface is good. Heads up display is very good and it now projects onto the windshield. Handles way better than the Highlander.
