We just got an '06 GT convertible (150 miles from home). We averaged right around 25 mpg @ 65mph; we were duly impressed. Believe it or not, the Crown Vic we traded in would get 24-26 mpg hiway; our '89 Cougar (supercharged XR7) is good for 25+ hiway also. My '04 Hemi Ram QC 4x4 will knock down 19-20 hiway after some mods; Fram CAI, synthetics and a "SuperChips" programmer. The worst of the bunch is my 1963 Chevy BelAir (400 small block, 4 speed......); it only gets around 16mpg hiway. Thank god the Harley is good for around 45mpg. Rats, I just realized we have too many toys! Anyone interested in a clean 1989 Cougar XR7 w/87,000 miles? It's in the "Other Ford Cars & Trucks" for sale forum.
