Good comments... the Ad you showed Lionel is my point... 1600 hours to a 1800 TBO and poor radios... an engine overhaul and you'll be near $30k investment, not counting all the other "frosting" stuff, like interior, plastic, paint, seats...
I paid $28k for my plane with new paint, interior, and decent panel and 86 hours smoh... I have about 140 now...
You can add up the items in my panel and accurately estimate that I'm over $40k into this plane. But, I can "see" the investment everytime I fly... works for me... but, I've maxed out anymore $$'s into this one...
I gotta run up to Prescott, AZ to look at an Aeronca Chief!!
bye..
