Ive seen shows like Gas Monkey, Pickers, etc who find barn finds and just jump them or do little to no maintenance and go joy driving/ reselling them as is.
I flipped vehicles for a year and most were a total loss even for a few years sitting. Some the engine bearings rotted away, some had leaks and the electrical system, fuse block was corroded over, interior filled with mold, fuel tanks full of varnish that use to be gasoline. Engine, tranny, etc with several ounces of water in them. Brakes rustedly engaged, engines you need a braker bar to free it up as the rings rusted to the cylinder, etc.
You can fully restore a car like in this photos for little to nothing, go for it.
