That is a good question. Does it have any accessories such as a winch, roll bar, windshield, tracks, canvas cover, etc? What engine does it have? Have you ridden in it or driven it? How is the operation of the engine and transmission? How are the bearings and axles? What about the chains and sprockets? How are the tires? Does the wiring look good or has it been spliced, cut, repaired, etc? Has the machine been restored or redone recently? There is a lot to look at and to consider when pricing these. If it is a good turn key machine with some accessories and little to no maintenance needed then the price may be ok but if it needs work and has no accessories then that price is high. I would guess a machine that old will need some work unless the owner has really kept up with maintenance.
