Gah! I'm sick to death of hearing this stuff. 100% pure ethanol has been used for ages as a medium for storing metals that are highly susceptible to corrosion. It is true that ethanol is highly SOLVENT, and likes to dissolve lesser grades of rubber and plastic.
Certain rubber types, like nitrile, are unaffected by ethanol. Do you know how much more nitrile o-rings cost than regular ones? Nothing. Do you know how much more a better grade of plastic costs? Next to nothing. By GM's own admission, the cost of making a car E85 capable is about $7, and my bet is that it the cost of the FlexFuel emblem they stick on the back.
