When Cessna came out with the 1962 Cessna 172C, the list price was $9895. 889 of them were produced that year and many are still flying today. I know you have to allow for inflation and everything, but that 50 year old aircraft is worth about $22,000 today. Dan Howard has a nice one for that price, and Air Murray has one for $49,900 with 430 WAAS.
