I would see what’s available with rentals or a flying club near you. The fixed ownership, fuel, & maintenance costs will have you at least 1/2 the costs of a rental, lacking flexibility to get out. There is the partnership idea too.
With renting you can vary things some. At one time there were great flying clubs at many military bases, seem less common now. With aviation interest there is usually rental options near military bases.
I also don’t think burning holes with your C-152 is all that valuable of flight time, though it is flight time.
