Who are you to sit in judgement of who is overextending themselves? You need to visit the real world, talk to the average Joes out there and get a feel for how they are getting by these days. There are plenty of people out there who need new cars, just like the ones the employees on this forum build for a living, who probably can't afford them, but need to try and afford them to get to work, take the kids to school, etc.
You're right, the question was regarding E-85 availability in an Explorer. So, why did you launch into a math tirade? If you would bother to look at the whole picture, you'd see that E-85 is an economic drain. The US used to export corn and most other grains, now it has to import them.
Not everyone thinks with their wallet... You must think farm implements that harvest all that corn run on water and don't pollute. Don't get me wrong, I love trees, I just don't pretend to hug them.
