I'm not surprised if you let the car warm up a little in the driveway, back it out of the garage to wash and then back in again, spend some time tuning it in the driveway, run around town on short drives, etc. None of my 427 Corvette, tuned Lightning truck or 67 440 GTX can beat 8 or 9 mpg for all of the above reasons. 7.5 mpg on the highway is a little steep - my Vette with 4.11 gears can probably beat that very slightly on 55 mph highways.
