Fractional Ownership
From http://www.fractionallife.com/:
"Fractional ownership and asset-sharing gives you an ideal way to get the most out of your investment by purchasing only the shares or time you require from an asset. All other aspects are split - both the benefits and the costs, amongst a limited number of Shareholders or Members. Fractional ownership means you physically own a percentage of the asset until you decide to sell. Whereby, opting to join an asset-sharing company eg. a private member supercar club is an investment in the time and pleasure you have with that asset."
