Looks in real good shape. I would agree with the $3k-5k range cleaned up. I bought a restored super hang on ride on for 3k, and these are less common. This looks in pretty good shape to be honest. Even if it wasn't functional you could probably still ask for a bit over 1k as-is assuming no major bespoke pieces are missing. Though given the logistics and size of moving it... could still take some time to move at that price.
