The value of something is only what someone is willing to offer for it. It makes absolutely no difference what it cost the seller.
When I purchased my TM and Van set up, the list price was up there, well up there, but with discount etc. cost me £46,000. Just a couple of months later, due to the passing away of the owner, an identical unit came on the market purchased around the same time as mine. It was advertised but eventually went for just £25,000, as no one offered more. It dawned on me that although I had just paid £46,000, it was actually worth £21,000 less, if i came to have to sell it, and maybe I would be lucky to get that. It just shows that it is no good saying " It's worth more than that, I paid £..... for it!".
