I once needed to store a car in a storage facility for a little while. It was fairly painless. I could have gotten a covered garage style space but instead I rented an outdoor parking space for an incredibly low rate. They also happened to have a move in special they gave me, its as if they don't like making money. Since the car was in working condition all I had to do to store the car was have it licensed and insured in my name and store it with a quarter tank or less of gasoline. The only real restriction was that I could not work on the vehicle on the property, but I guess thats still pretty reasonable.
