I just got back from my first road trip to Atlanta, including interstate driving from 60 - 75, varying, and city driving as well as four-laned road driving 45 - 50 with towns and stoplights. I am so pleased at how well the car handles. Such a joy to drive. I didn't find a noise issue. It seemed quiet to me. The mpg was simply amazing -- 66.3 miles per gallon. How I love this car!
