I beleive the market for EB is like anything else being sold, there are times when prices are high and when they are low. I believe you have a very nice EB there and well worth 9000.00 plus. When I bought the one I have just a few years ago I paid 8500 for it and its no where near as good of condition that yours is in. Mine had alot of money dumped into the motor/ tranny and which is why the price was up(he was just trying to get back what he paid for new motor/tranny) and not all that fancy, just a 302/C-4, but were new with hi-po parts on them. My EB still needs alot of work( needs a frame off really ) but it runs great.
So people will pay what they will pay but if I had 9000, I would take yours quickly ! Well worth it !
edit: of course I would have to stick some fat 38's on it and about 3 more inches of lift ! But other than that wouldnt change a thing. You have good taste in EB design. I like that color !
