That 280 is gonna cost you in gas, thats for sure. It will get about 1/2 the mileage of a 617 turbo. A couple people I've known that had 280's averaged around 12-13mpg...on premium! (currently 2.97 a gallon here) Thats one thirsty sedan you've got there. If I had one it'd only be my Pleasure/Sunday driver.
