Default Convert to e85?

Hey guys! Forgive me if I do anything wrong here, I just joined up as a first time Mustang owner, and I'm completely new to the forums!

I just got a 2000 Ford Mustang Base Coupe, and my commute is about 45 minutes to work, and I was hoping I could switch over to E85 to help shave the cost on fuel...Being new to Mustangs I have no idea how they work, or what I'll need to convert to E85! I noticed some users on other sites have talked about tuning, is that necessary, or is that more for racing? All I need is to get to work and back, nothing special. Will I need to replace any parts? Will I still be able to use regular gas and E85 interchangeably without having to reconfigure the car? I greatly appreciate any help!

Here is a site dedicated to your question.

Keep in mind there is still a lot of unknowns about E85 gas. A lot of people have claimed to have had severe corrosion due to the way E85 effects fuel systems. Other people have claimed worse performance and MPG in fuel flex vehicles compared to regular gas. I personally cannot say as I've never used it, however those are comments I've heard first hand from people that have used it and had problems with it.

E85 quires MORE fuel to burn, which also means increasing the size of your fuel injectors and pump.

With the increased volume you'll consume, the cost of upgrading the fuel system - you won't actually save money from making the switch unless you're running a very extreme performance set up.

Short version: Don't do it if you think it's going to save you money. It will end up costing you more.
