The $80K price on most GA aircraft indicates the engine is time expired, "on condition" and prop close to overhaul.
Expect to need a second mortgage to pay for an engine and prop overhaul.
I've owned seven aircraft, seven boats and five sports cars over my long life, the rest of my earnings I spent foolishly.
I recommend a Bex Powder and a quiet lie down. Far cheaper than paying $80K plus for something which in reality is probably worth 10 cents per kg at Simms Metal.
