I just wanted to give everyone a heads up. I have my new civic for about 1300 miles now and i am averaging 20 miles city driving and 30 highway. mixed driving 25-27mpg. I am to bring the car back to the dealer to get it checked. The car doesnt coast well. It actually slows down on slight declines in road. Very disturbing since i purchased this car for the mileage. My 2 cents.
