Tech, if ya think back, a few months ago somebody sold a Crossfire on EBAY (or maybe Craigslist) with a newer SLK nose grafted on it. On a whole, I don't think it was very well received by the Forum.
Anyway, an SLK is supposed to have a .34 Cd, so maybe that's someplace for you start.
Keeping your spoiler down is another way to make it more aerodynamic, less parasitic drag (just stay below 90 mph). I gained better than 2 mpg by keeping mine down. It isn't why I keep mine down, but the extra MPG is a bonus.
Use skinny tires, like the old 2003 SLK's used. What you lose in handling, you'll make up in the 1/4 mile, .34sec. quicker. Less rotating mass.
