Stop in for a cup of coffee

I'm going to list the Barracuda soon and pondering a price. I've looked at similar cars for sale and with this one being a 1 of 9 known to exist it's a crap shoot. I have a great friend who is a well versed 67-69 Barracuda expert and he said 80K. I was thinking 70-75K. I guess if I went 80K I can always come down, but you can't go up?? I don't have to sell so some low baller will never get it. Any suggestions??
