As said in another post, the value is directly proportional to what the parties are willing to sell / buy for !!!
(S + B) / (HB + T) = Final Sales Price
S = The value that the SELLER is willing to sell the product for (perceived value)
B = The value that the Buyer is willing to buy the product for (perceived value)
HB = HOW BAD the Seller wants to sell and/or HOW BAD the BUYER wants to buy - this is usually link to emotions.
T = Time
So is someone is willing to pay $25K-$23K for your VX and you are willing to let go for that price...Go for it!!! Personally I don't think you will find many people interested in buying a VX for that amount. I think is insane, despite all the mods and effort put into it. Doubt you will find someone else at that $$$ level any time soon.
