Our Sonota is very smooth and quiet.
We are getting exceptional mileage. Between 28.5 and 29.5 mpg in everyday driving. 25 mile round trip commute to work.
Our Sonota looks and feels like a quality car. I have yet to hear any kind of a rattle or squeak on our winter ravished road. The paint is perfect. Doors close with a solid thunk. We have had the car for about 2 months & no problems with anything.
