I think I'll store my IT-A Rx-7 outside this winter, probably on its open trailer. I'm in Colorado - winter ranges from -20F to 70F, relatively dry.
I drained the coolant, disconnected the battery, it's on scrap tires, loosened the tie downs, and has a good quality car cover.
Anything else? Would mothballs discourage the little animals of the forest from eating the wires?

Separately, a friend in NY state has a VW-based kitcar and wants to store it outside. No coolant, of course. Anything special for this car?

Thanks!
