Both are manuals. I usually get 30-35 mpg with the silver one depending on traffic but I have gotten 40 mpg with it when I keep it under 60 and in fifth gear. I haven't calculated the milage on the 09 yet because I try not to bring it to the Bronx since I park on the street. No mods except the lowering and wheels on the 09. The 04 has a better stereo and an armrest I built and upholstered since they didn't put one in the 04. I didn't want to mod them too much because I drive so much I need them to stay relaible.
