I'm surprised that the floors and rails look pretty good as it appears all the outer panels are in need of replacement. Roof, quarters, fenders, hood, dutchman's panel, doors possible rockers and a pillars. Likely with the rear quarters in such poor shape, the inner's are in just as bad of shape. The trunk is beat as well since there was obviously water getting into the trunk through holes in the dutchman and deck lid rails.
I have to say this car is pretty beat. And I don't like saying a car can't be brought back.
Not having the fender tag hurts the rebuilding of this car.
You would do yourself a huge favor by looking for a build sheet as that might be the only thing that puts this car back on the road again.
Perhaps there is a restomod guy out there looking for a car to make what he wants.
Problem is with a car in this shape it's gonna cost minimum 40K, most likely 50K to bring it back to par. Not meaning an OE restoration but a good driver quality car restoration. Then the car will only be worth 35K to 40K on the market. 2-4's just don't hold much more value than 40K at the top end. Even if they have 80K worth of money put into them.
What's your idea of value on the car?
Does the motor turn over?
Is the motor numbers matching?
Is the tranny numbers matching?
Do the radiator and cowl stampings match the vin?
Is the color b7 or b5?
Find that build sheet.
