Be careful I owned a quarter share in a retractable and it was a disaster because of one member.
He landed it heavy damaged the prop and nose wheel meaning a shock load test and no access to the plane for a good six months.
The same idiot landed gear up going around with a bent prop this time 9 months no fly for the rest of the group.
Accident damaged we sold it getting half our original money back.
While some groups work well be very selective about the pilots you take into the group as well as making sure usage and charges reflect the group or one guy will end up doing all the flying at the expense of the rest.
I would rather pay more per hour and walk away if anything goes wrong than by buying into an expensive headache caused by others
