Matthew,
My experience of the 964 is it has not got to the depth of decay that the torsion bar cars have. An average pre 74 car was a pure basket case 20 years ago, an average pre '89 car has now reached a poor state in areas of B-Post, sills, A-pillars, Scuttle front & rear, wings, front floor, fuel tank, rear light area, sometimes the roof rails.
What you seem to have is a lovely original Coupe that is in need of a tidy up. Anything you spend on it within reason will not be lost - the 964 Coupe is appreciating as the good ones get fewer.
The areas you will need to attend to are the Windscreen surround, (shell flex abrades the paint over decades and rust starts) sills behind the covers but nothing compared to a 3.2 carrera, scuttle where the wing meets it and down the inner wing top edge (remove wing to see) headlamp bowl area of front wing, tail-light area of rear quarter, engine tin, (try RedTek and speak to Roger for Fiberglass tins as opposed to parting with £1000 for new originals which will go the same way), rear bumper mount area may be corroded.
On top of that you have all the brake pipes, fuel lines, brackets, clips and rubbers etc.
Lots of it can be reused if you are careful.
They are generally built very nicely for DIY repairs.
Loads of specialists will rob you because its an appreciating car.
Good luck with it
George
