The Elio does not have a bottle for windshield washer fluid. It has a place to hold the gallon jug washer fluid comes in, and it also has a suction hose to go into the jug. When empty, the hose is pulled out, the old jug removed, the new jug is inserted (minus the cap), and the hose inserted. It saves them the price of a bottle for washer fluid, and nothing is spilled. Slick.
This vehicle has a place for a 5 gallon can of gas. When used up, the hose is pulled out, the old gas can removed, the new gas can is inserted (minus the cap), and the hose inserted.
