Give it a little more time if you really like the boat, I guess. Then you have many other fish in the sea.
Do me a favor though... PM or start threads on the other topics. (Trucks, Do you know me, etc.) While some conversation in the markeptplace is inevitable, we are trying to keep the for sale threads just about the item being sold. Primarily, questions to the seller and answers from the seller.
In the case of this sutphen, if I really liked it I would reach out to the seller again and see what's up. If the boat is anywhere remotely near you... see if you can go see it. Maybe the seller has camera problems. Thanks for helping out with the discussion thing, and good luck.
