Depends on what "restored" means to you. I'm currently restoring mine, and to this point I've rebuilt the engine(331), rear, replaced the trans
, all the brakes (5 lug 4 wheel disc cobra setup), new paint, refinished the entire interior (carpet, headliner, re-dyed all the panels, dash, fixed wiring, etc), replaced weather stripping on the entire car, strikers, hinges etc...and I'm not done yet. To this point I've dropped roughly 15k in parts and materials (materials meaning paint, dye, etc).
Is that the level of effort you are talking about, or are you just talking about fresh paint and some weather stripping? Because that will make a HUGE difference in what the car is worth.
