I'm not sure that's fair on the seller or something I'd feel comfortable with really. I think everyone just has to bid on it as they would normally and accept it's not going to go cheap.
I'm starting to feel guilty and feel like maybe I shouldn't go for it, as however much I want it I still know it would end up hanging in my garage quite a long time before being built up, however quickly I intended to do it, because that happens with all my projects, due to how much I have on.
