That said, my wife's 35i consistently gets 23.7 mpg (by the dash readout) on her 20 mile commute over a winding mountain road and when we bought the car home from Ariz. where we bought it (a 600+ mile trip) it got 27.5 hand calculated mpg. And that was doing an average 75-80 mph.
Did you calculate: 600+ miles/XX gals of gas you had to pour = 27.5 mpg?

If so, that's something I could most definitely live with, especially going at 75-80 mph!!!
