 I have read many other reviews from very satisfied customers to whining and moaning/groaning.  Its a Nissan Sentra, not a Lexus.  For the money it is a great car.  I am returning a 2013 from lease and picking up a 2016.  I have had 0 problems with my 2013.  Gas mileage is fantastic.  I drive a lot, mostly highway.  Average mileage per tank was 375.  Pretty good considering other cars.  I occasionally hit 400+ miles per tank.  It is comfortable to drive, has enough features for me.  I am pretty simple.  Good radio, Bluetooth for cell phone, convenience buttons on the wheel.  Folding back seats make good added storage.  It IS lackluster in acceleration but that is due to the CVT transmission and lack of horsepower - this engine and transmission are built for economy not speed.  Again, its a Nissan Sentra, really the 2nd level sedan Nissan offers (just above the Versa).  Great car for the money.  Best gas mileage, like all cars it is at 55mph.  Don't expect 40mpg on the highway if you routinely drive 70+.  Looking forward to the 2016 with added standard options like back up camera and streaming music via Bluetooth.
