....The srt is spec'd at 6 mpg city and 14 tops highway .The 5.7 is more than double those numbers mpg.

I agree that he is most likely accurate with the numbers he posted but the SRT fuel mileage you posted are a little off. EPA estimated the 6.1 as 14 city/20 hwy compared to 5.7 hemi which gets an EPA estimated 17 city/ 25 hwy. Real world it (6.1 hemi) should get at least 10 city/15 hwy, depending on your driving style. Also your Corvette C5 sounds nice and I hope you can get the challenger you want at a affordable price.
