Well, the E85 option when building a car through GM Dealerworld, the cost difference in a car that has Flex Fuel and one that does not is only like $8.00 and change. Also, for those of you who don't know, corn is not the only product that we can make ethanol from. Sugar works as well. Another fun fact is that while you lose 2-3mpg when burning ethanol, the E85 actually burns at a higher octane rating than premium gas and therefore makes your engine perform better all around.
