5 years ago my FIL purchased my BIL an acousting guitar for $100. I think it was a "Honey" or some shit like that.
After some family drama, the guitar ended up being in a closet for 3 years. My dad is currently using it. Today he tells me that he really, really wants his own guitar for Christmas. I asked him if he would like to own the guitar he learned to play on and he said that would be great.
After some debating (mostly me pointing out that my FIL was being an asshole about wanting to keep a guitar that sat in a closet for 3 years) he finally agreed to sell it to me.
What do you think is a fair price I should offer? Its 5 years old and doesn't have a case. He only paid $100 for it in the first place, so I was thinking under $50.
