It is possible he will get close to what he wants. If there is a paucity of IFR GPS equipped 150/152s out there (and I am sure that is the case), he might find the person who would have bought another plane and installed the same equipment and figures that s/he can just buy this for around $40K. I believe he has gobs of money invested.
I remember gulping at what I paid for Wilbur (and what I have put in him since) but I am SO glad I bought him. I paid a lot but I figure that I will have him a long time (hopefully forever) so it really does not matter in the grand scheme of things.
