Buying Used Board Help

Hi,
I know this board is not in the greatest of shape. I wanted some knowledgeable opinions on the damages you see and how much you think it could be worth or if it's even worth buying/using. I will have to purchase a fin as well as it was broken off. I will probably go surfing 8-10 times per year, I live to far away to go much more. Just looking for something that is good enough. I'm an okay surfer, but really know nothing about the boards themselves.
Thanks for your help
