This thread is interesting, a valuation program is really good,, so let's flip this to a "auto blue book". Anyone always only pay just the "blue book" price? That part only works when you have a trade in,, try buying the same thing the next day. So, to me the single biggest issue is,, it's not Vref,, it's the lack of pilots looking to buy,, Lack of pilots being turned out, to much legal stuff to contend with, I suspect if there was a big demand from buyers, airplane valuations would go up. Interesting that here, buyers only want to pay based of a valuation. So, not that I'm selling, but if I was, I'd set a price that I would expect to get for my plane, and the ones that would like to get it for pennies on the dollar,, no big deal,, go find another that is lower valued. Does this work,, yes if you have a very nice plane,, if you have an "average plane" well, don't expect to get more for it. When I sold my 172,, and I'd spent a lot into it to get it fixed up to my expectations, I set a price that was high for a 172,, and would you believe because it was known that it was for sale, 3 people started making me offers that were higher then my starting price. I suspect that if it had of been "average to the available 172's" folks would of tried to offer me less,, at that time, the the Vref was fairly low,,,,
