There are a few hundred thousand vehicles between the two vintages you listed that don't do so well on E85. My point in this lobbying adventure is to inform people that RIGHT NOW you can buy a car that runs either gasoline or a more patriotic E85 and give up nothing except maybe a few more bucks in some cases. I'm glad W decided to advertise this at the SOTUS, but I am not happy that he chose to demonize petroleum in the process.
Provided a market demand remains firm, some automobile manufacturer will make a line of vehicles available with an engine optimized to ethanol.
