I was going to give up but what the hell
If you can't sell it for the prices backpacker mentioned then the valuation is not accurate. The Market Value of something is not what you offer it for sale at, it's what someone will pay you for it.
Chilli and bose are I suspect not working on Market Value. The Market Value of an airframe with a half-life engine in it is not the same as one of similar age and condition with a zero-timed engine in it.
So you get an airframe with a zero-timed engine worth 30k, you then fly 1000 Hrs in it. Is it still worth 30k? Of course not. Let's say the group put 15 quid an hour into an engine fund. Is the airframe worth any more because they did this? No.
