I think it's cool as heck...and I do want it. There are, unfortunately, a lot of things I want and I'm not sure I'd buy it, but I think the price looks good on something pretty dang unique.
As far as the prior owner not being thrilled with it, not everyone is in the hobby for the same reasons. The owner might have loved it, but many folks view bikes as a 3 year and replace item. The prior owner clearly has the money for the hobby, and a new bike every few years is far cheaper than many other hobbies. Not everyone uses the same approach most here use.
