I think the reason for storage is some people don't use their cars as daily drivers. I for one don't, and because I don't my car stays cleaned, waxed, gassed, and ready to rock my world when I call (unlike my wife

).
I detail and work on my car during winter, nice to have the down time to fix long lead tasks (rework and paint on all four rims, total brake job[rotors, pads, lines, fluid], etc.) Boys and their toys.
