Both my vehicles only get 15mpg in the city or maybe 20mpg on the road, a 3000 mile trip would over 160 gallons of fuel, with a Elio it would only take 36 gallon with some left over... in Portland Oregon the gas is about $3.21... so over $500 for fuel or drive the Elio and spend only $115 in fuel... that means I can spend my cash on other things, then imported oil...
