I very much doubt that people rent out expensive aircraft like the Cirrus at the prices quoted, the truth of the matter is that most of the non equity groups are a business that is built on the basis that the monthly fees collected will more than cover the costs.
Usually these groups are quite large and full of members who all want to fly at the weekends, the truth is that the last thing the owner wants is anyone flying the aircraft as he makes far more money when the aircraft sits on the ground doing nothing. The nightmare sinario for the owner is when a very good weekday pilot shows up and flys the thing a lot during the week and eats all the owners Proffit.
