I traded for my Bronco, and the agreed value of it was 11,000. I wanted 15,000 for the heep I traded him, so he through in enough extra stuff to even up the trade. So I feel like I gave 11,000 for my Bronco, and have at least 5,000 more in it. That being said, when I set my mind on an EB it wasn't to awfull hard to find (I already had one when I traded for this one that I had bought a couple months earlier). But I have been looking for a 69/70 Mustang fastback that I could afford all my life, and you don't find them in any decent condition for less than 8,000 dollars around here, if you can even find one. The last one I considered was a 69 with a solid body for 6,500, no motor or tranny and 4 lug wheels (6 cyl drivetrain). Probably should have bought it and built it.
On the other hand, if the car doesn't hold you and you want a EB that bad, sell and buy. I would put the price you want on the car and not take less money, you don't want to waste all the money and hard work you have invested. And take lots of pics to remember it by!
