A Cessna 172’s value is just like a car’s – it all depends on the age, the condition, and what accessories it has.
A piece of junk bought as a fixer-upper with no airworthiness certificate can probably be had for under $20,000.
However, planes don’t age and deteriorate in the same way as cars do. Providing it is properly maintained, with all the maintenance logs in order, a fresh annual and engine overhaul, and fully loaded with modern avionics – a 50-year old Cessna 172 could set you back $200,000 or more.
That’s in the US – expect to pay more in Europe.
