Some of you are using logic and some are not. What Red_Zed is saying is you are basing one off of real world numbers and the other you are pulling from the invoice. So that 30mpg on the invoice for the c7 can very well be 32mpg real world. Just as the c6 was 26mpg on the invoice but you say you averaged 28mpg. Either that or the rental you had was a special build. In the end its a sports car they can only do so much on the gas mileage.
