Something different Building for MPG.

First time I've read this thread. Pretty interesting ideas. I am really thinking about building a /6 Duster if I can find one. I hope to get mpg in the mid 20's and it does not sound like that is hard at all. Even though gas is under 2 bucks, who knows how long this is gonna last. My Ram Charger is a pig on gas, I'd say it gets about 9-10 mpg. I figure, if I find a /6 car, I'll keep it that way for a while until my need for speed says I need to upgrade.
