Who Really Cares? I drive my lil Kia Optima about 500 miles a week on a 16 gal tank with a Frown on my face...
I drive my Barracuda on the weekends gettin 8-10mpg Grinnin' from Ear to Ear!

I care because this fall I'll take this car on a 2000 mile road trip and I need to know how far I can reliably get on a tank of gas.
