(Actually my geo died a month ago, so former owner)

More than once I took my Geo on a trip where the headwind was strong enough that I could not reach 70 mph. I still go 40 mpg on that trip, even though I held the pedal to the metal for over an hour. I do not see how an able person can get less than that in a Geo. (Obviously the disabled could, because the disabled need an automatic)
