Jay I sold my Cherokee about a year ago and it was a bit worse than it is today.
I did surprising well... I paid $20k about 9 years ago, put no upgrades in the plane, I just flew it the way I bought it. Normal improvements like an inexpensive upholster job.
I spent about $10 per hour for annual inspections and maintenance so maybe $11,000 over the 9 years and 1100 hrs this includes rebuilding mags, 2 new jugs, starter, and carburetor.
I sold if for only 20% less than I paid for it. I sold it the first week I told anyone it was for sale, no advertising, no subscriptions.
I didn't do some of the stupid things pilots seem to do: I didn't add the $11k maintenance I spend on the plane over the 9 years to the cost and ask $31k for it. I didn't spend $20k upgrading the avionics and expect to add that to the price I paid 9 years ago. I didn't spend $16k for a paint job and expect to get that money back. I didn't spend $20k on speed mods and expect to get full price for those.
A plane like a car has a value today and every day if you are realistic in your asking price you will get real buyers quickly.....If you are a jagoff in pricing your plane you will talk to every tirekickker in the world none with money in his pocket.
