I read somewhere that the highest time Cessna single is a C 172 which flies 8 hours a day doing low level pipe line inspection. It has 36,000 hours and is still going strong.
Granted not exactly apples to apples but I used to regularly fly a Convair 580 that had 97,000 hours and 156,000 cycles.
A light Cessna that is well maintained has effectively an infinite life. It is corrosion and poor maintenance that kills these airplanes.
