A friend of mine has owned a well taken care of M20F for many years. He's flown in on many Angel Flights but his hearing has gotten to the point he isn't flying enough to justify keeping it.
It's a really nice F with a 530W, STEC, custom leather interior, low time engine...
Let me know if you would like to get in touch with the owner...
I think he's thinking $70k but I am not involved except to put folks together.
