I checked into some of the local "abandoned" airplanes when I was searching for one. The owners seemed to think their "Cherokee 140" with 1700 hours on the engine and flat tires was worth over $40k? This was a common theme. Some had sat still for over 7+ years. At least in Arizona, most of these could be brought back to life, but not at $40k. Obviously. But why pay a tiedown fee of $50/month for 7 years to have an airplane usable only for parts? Sell it while it's worth something and let someone else take care of it. Instead of paying $5,000 in storage fees to let it rot into a worthless pile of parts.
We have a pop up camper in a storage lot. Same thing happens there. .???
