I don't remember the Elgin that my original post was about. But since then, I've parted a few bikes that I thought should sell complete but they didn't.
That black BFG above was a nice bike, but when nobody wants to step up and pay for the complete bike, and the demand for the parts outweighs the demand for the bike, you do what you gotta do. It used to bother me, but now, I just say, it is what it is. The bike was offered complete, there were no takers, it went to parts. Oh well. Looks like the parts sold pretty quick. Obviously there was much more demand for the parts than the bike.
