Push Start/Stop
 I drive a lot of freeway miles. This car is got the perfect balance of power, acceleration, comfort and fuel economy. CVT transmission works like a dream.  Get 29.4 average mpg: 80% freeway cruising at 72mph; 20% varied driving about town.  Negatives: 1) Tail pipe smells in the cabin initially. Whatever it was seemed to burn itself out after the first 8,000 miles. 2) Push Start/Stop button works great except...frustrated with the stop button instantly killing the sound system along with engine. Sound like a minor quibble but when I get to my destination sometimes I want to hear the rest of the song or talk radio topic without having to continue running the engine.
