If you are buying an original good paint all correct non restored $1500 or less is usually a steal I would say. If you over pay then You just have to have That 1. Value & Worth are Subjective here. I can't see paying that for Any Bike but I am not a collector in the aspects of resale value or rarity right now
I was watching that one as well ,restored if done correctly are worth some money ,this one looked good I would think 1500 was a okay price .the 18 percent was high so always have to take that into consideration .also the 24 inch size is the most common ,the tricycle was a good buy ,way rarer then the 24 .that should have brought a 1000 easy .
