Using the a/c intermitently fetched me some decent mpg figures. But whenever it is feasible, I crack open a window (or the sunroof) and use the vents.

I'm with ChopsQube, a couple mpg loss is worth it to not sweat like a horse. But there is a lot to be said about finding a happy medium between windows down and ac cranked full blast. In my van I'll turn off the a/c as much as possible or turn the blower to the lowest setting; makes me wish for a thermostat inline with the a/c switch.

Be careful mentioning mythbusters around here; you'll be told how unscientific they tend to be.
