My wife and I just got back from our vacation. Thanks to all with their suggestions. We put about 3200 miles on our base black coupe and averaged around 28 to 31 miles per gallon. We paid not more than $3.99 per gallon for premium fuel. We were able to see the Grand Ole Opry, 16th avenue, Indianapolis Motor Speedway, The Biltmore Estate, Grandfather Mountain and so much more. Best drives included the Blue Ridge Parkway, Hwy 80 by Lake Tahoma in North Carolina, and of course, the Tail of the Dragon! Just fantastic! We stayed at great Bed and Breakfasts along the way most notably The Inn on Mill Creek in Old Fort North Carolina - highly recommended! Thanks again!
