It makes me wonder what the difference is between my car and the ones that are set up for flex fuel.

...not t hat I'd use E85, but I want to understand the differences.
Main difference is fuel pump and fuel line materials. ECU also has ability to sense what fuel you are using. I suppose it has different fuel/timing maps for E85, but I have no proof.
