What is the proper way to store a car for a year or more?
Paul , rather than getting a bunch of conflicting ideas or some of us forgetting something just do a Google search ( storing a car ) will get you articles and videos so you can choose your own plan.
Agree with Volvo_V70 as to procedures for storage.
But one thing I learned from personal experience, after you do all the prep work, cover the car with a quality car cover. I just used old sheets, after 15 months the car was FILTHY, required a lot of washing.
