Yeah, just to answer that part of the question for 'ya, no one is going to buy a C-150 for $50k.
C-150s are selling for around $20k right now, with many less than that and a few for more. There are none sold for over $30k unless they have something unique, like a 150 HP engine or something, and even those are selling for less than $50k.
It does make an economical way to get into owning your own plane, though.
