2004 4dr Sedan 260-horsepower 3.5L V6
5-speed shiftable automatic RWD		 Currently get 25-27 highway and 21=22.5 in the city. Live in extremely mountainous terrain, so mpg would be higher in a flat area such as Nebraska or Kansas. I would have added a 6th gear and kept the power. see full Infiniti G review

5-speed shiftable automatic RWD		 At the very best, my combined fuel economy never got above 20.4 MPG and is recenly under 19. see full Infiniti G review
2003 4dr Sedan 260-horsepower 3.5L V6
