I need some serious help. I own a Span America. Year/model unknown. My dilemma is that I'm selling it and I have no idea of the value. I have had three offers. Two were really low but last was rediculoslly high. I don't want to give it away but I don't want to sell it for more than its worth (I like to sleep at night). I want a fair price but I don't want to screw anyone in the process. Best I can tell it's 60's but with all of the research I've done, I can't find this model anywhere. I almost took the boat to the dump to modify the trailer but there are no cracks, all of the gauges are good and everything seems to be intact other than the windshield and deck. I'd hate to throw away the spedo or tach that a guys been trying to find for 15 years to complete his project. I'm NOT pandering my wares here, I'm simply looking (and praying) for some knowledge or direction.
