stevests, I hear you. Outside isn't my preferred choice, but I've read that good airflow around / through the car will help keep it dry, or at least mitigate condensation issues. Plug the exhaust, and keep mothballs and / or dryer sheets tucked away inside.
I'm concerned about a car insurer (Hagerty / JC Taylor) denying coverage if the car is not stored on my property, like in a rented storage unit or garage. And I'd feel weird renting garage space and letting myself in to someone's private property when I don't own the place. But that's just me, overly cautious.
