I watched the video too; very interesting and I wish this fellow luck.

On the other hand, someone obviously was planning to restore the car, and then they bailed for some reason, and were willing to leave a lot of new restoration parts in the car. Why would someone do that?

One idea would be that there is a hidden problem not yet unearthed by the video-maker; perhaps the engine is blown? At this point he looks to be an enthusiastic and lucky person. Assuming that he posts the sequel(s) to this first video, there may prove to be more to the story.
