I've somehow missed this topic for nearly the past month. Great idea! Its always helpful to have a bit of a push to get higher mpg.
Years ago (2009) I hit 70+ in my 1997 Toyota Paseo twice. P&Ged the crud out of that car haha.

Ironically, I highly doubt the much more economical Mirage will ever achieve such a number. I'm finding it hard enough to get a 60 mpg tank. The car is just not aerodynamic enough mainly due to too much frontal area. That is where the Paseo really had the edge, small frontal area and decent cd.
