An airplane is worth whatever someone is willing to pay...at least to that person. I'd guess the owner of this particular little Cessna probably paid a premium price, then again paid top dollar hiring out all the upgrades he wanted, over ran his headlights in the process and now finds himself buried in the money pit he created. Now, for whatever reason, wants to sell it and is hoping that one insane buyer will come along and rescue him. Maybe that will happen, but not likely. I agree with Fred's prediction that some day in the future the airplane will sell for about half the present asking price.
What you invest in an airplane, or what it would take to duplicate one has little relavence to its actual market value.
