$20,000 seems kinda salty. I just sold my beloved 73 150 for $19.5 and it was sharp, good airframe and eng hrs and equiped with a KX 155.
From what you described the plane sounds good, the price would make me run. What does it have for radios? I may be alone about this but I think a good stack of avionics is very important in the price of a plane.
