I need the collectives help in helping a friend determine what would be a fair value for his 911.
It's a '67 S. He's had it a number of years now (I'm not sure how many) and it's been off the road for a lot of them.
I have a PDF doc that describes the car at the time he bought it from my brother.

He's trying to figure out how much it's worth as he's getting ready to sell it.
He's not Porsche savy and I've been out of them for too long to tell him what it may be worth. His research has shown him prices all over the map as far as prices for '67S's.
I don't have any current pictures to show you.
Thanks for any help you can lend me (and him).
