put a good car cover over it so no birdchit can get to it

pour stabil in the fuel tank fill up the tank with fuel, way full
then and run it a while so it circulates through the system with the stabil in it.
couple of minutes should be fine

If the radiator is busted, make sure to fill it up with coolant while before you run it
ideally the closed thermostat would allow the engine to run with the coolant
do not drain it, the coolant will protect from corrosion

perhaps give the seats a leather treatment so they are ok for a while.

yes, do disconnect the battery.


tires, well, no use, standing still will make em flatspot.
if you can, put the car on jackstands..

perhaps put some pest deterrents to ward of critters that might nest or chew through cables

Not sure what the deal is, but accident & legal issues?
sucks man, hope it works out for you
