I would pull the wheels and store them inside if possible it keep dryrot at bay..,,also buy moisture bags to put in the floor and seat..these pull moisture out of the car....get a quality cover..don't use plastic....fill the tank full of gas with some fuel stablizer..this will keep it fresh and keep out moisture from rusting the tank..I spray my rotors,parking brake,throttle cable,door hinges,door locks with wd-40. make sure you heater vents are closed
