IMO this is a $1000 car, based on what I can see.
No more than that, because there are a LOT of unknowns, and any missing parts will be a PITA to find.
There are lots of 65-only parts (like driverside motor mount and door locks), and then 65-only, Fury-only things, too (some body panels and trim, brakelights, etc).
No less than $1000, because it's a 65 SF, lots of parts there, and it isn't folded in half. 65 SFs aren't growing on trees anymore.
If you find it is verified to be solid underneath, then maybe $1500.
And you really should inventory all the parts then. For example, if there are no extra taillights included, it could be $200+ just to get a set of used lights/lenses. 1-year only.
But any more than that and you are better off finding a more expensive/better car to start with.
