If I were you, I would use that as my project car. Do the mods you would never do with your Duratec, like extreme weight reduction (stripping the interior). Ya know, stuff like that. That's what I would do.
Man, tires and battery is no biggy. You should take it.
And I don't know how the insurance is where you are, but in Florida, windshield replacement is free.
So, for less than $200 you can acquire this car. It's up to you if you want to sell it or drive it. You can sell it at a steal of a deal price and still make decent money because it didn't cost you much. If you do decide to sell it, why not have some fun with it before it goes. Tray sliding, neutral bombs, off-roading, anything that you would never do to your car.
