Personally I think it boils down to seeing what is there and being experienced enough to understand what truly needs to be done. I see this as a car that honestly needs a total restoration to be anything more than a neighborhood cruiser or 'garage art'. It looks like many items are excessively worn to be safely used for anything else. Look at the front spring and see how it is sagging and leaning. Maybe optical illusion?? The radiator shell appears to be a reproduction and the front apron is missing. Rear bumpers look repro, the pop-out switch looks like one of those "Made in Spain" units that were too long and didn't work well. Looks like a Powerhouse lower water pipe, and the body aprons look like they do not have the hump?? Mismatched assemblage of a car using many 'Rick-pack' reproduction parts??? If so, what is the true value of that??
Bottom line, for anyone that wants to drive it and use it to go places, then it will need a new top, some major interior upgrades, probably some mechanical renewal and new tires/tubes. IMO, it really does not matter whether the car is this nice or whether it is much worse, the amount of restoration work is about the same. By this I mean, it really does not matter whether the present brake drums are worn just slightly oversized and still have some black paint on them, --or whether the drums are rusty and have deep grooves worn in them. In my view they are worth the same amount as they are essentially cores that need restoration (i.e.: drums replaced).
Look at the L/R fender. While it still has paint, it appears it has major issues in the bead area. Is it really any better than a swap meet fender that has surface rust all over it and a minor broken bead? The same mindset can be said for the engine. Even if this one runs but is worn out, --or whether it hasn't been started in years, the value placed on that engine should be the same. This is why I advise people not to get caught up in "patina" or by "barn find" looks.
The reality is very few people listen to that advise and falsely convince themselves this car is better than one sitting out in a field. Again, in reality both type cars are needing a full restoration and the costs of the restoration are roughly the same. The downside is this car will likely be sold for more money simply because of the "packaging" (i.e.: the patina). We all know in the world of sales, ..."packaging" is everything!!
