I also agree with the others that will be hell of a money... Think about just buying a used car... always something is broken, need repairment or to change some items etc etc etc.. even cheap things are expensive when allt he stuff comes together... all the amount of money spent on the plane could be spent on flying....
BUT... on the other hand... give it for rent can be a good business.. BUt then you need to get used to that fact, even if you want to fly, the plane can be out in the air. And you as the owner need to wait for your own flight.
