Don't start it, just keep it charged and let it sit til the day you're ready to drive it. I guess it's better to let the engine sit then to start it every few weeks and not drive it.

 

why do you say that?

 

Might I suggest to anyone that's going to be storing their stang outside for the winter to pick up some DampRid? It comes in refillable cups so once the desiccant is used up, you just throw away the old stuff and add new fresh. Even though mine's stored in the garage, I still put a container in the rear hatch and I go out every few weeks and check on it.
