Parting it out would get you the most, by far.
With the volume of cars out there it may be a bit before someone would "need" it as a full parts car, but it is likely to happen eventually.
You might also be able to fix the battery. The dealer won't even try as they are not "serviceable", but can't really say what it would take.
If you do need to move it, get some offers and let us know what you're seeing.
