 Since 2006 many new FFV models in the US feature a bright yellow gas cap to remind drivers of the E85 capabilities, and GM is also using badging with the text "Flexfuel/E85 Ethanol" to clearly mark the car as an E85 FFV.A major restriction hampering sales of E85 flex vehicles or fuelling with E85, is the limited infrastructure available to sell E85 to the public, as by October 2008 there were only 1,802 gasoline filling stations selling E85 to the public in the entire US, with a great concentration of E85 stations in the Corn Belt states, led by Minnesota with 357 stations, more than any other state, followed by Illinois with 189, Wisconsin with 118, and Missouri with 112.Only seven states do not have E85 available to the public, Alaska, Hawaii, Maine, New Hampshire, New Jersey, Rhode Island, and Vermont.
