I would be content with anything over 10 mpg consistantly. I guess it's a min. of $10,000 to get these cars to where they should of been in stock form. By that I mean, fast and not easily broken. And anyone who has boost knows, it is very hard to stay out of boost. Everytime a car gets ahead of you. You push the pedal a little more. Or hell, just for the shear ability to hear it spool up, or dump off. It's just addictive.
