In exploring the stolen cars/car parts theory, I've done a bit more digging and came across a couple of things I'd thought I'd share.
One, the cars at 4077 UHR have been a rather recent addition. In looking at Google Earth using the timeline, I found that in May of 2012, while there were some junk cars sitting around, nothing near the extent of what is there now (with the most recent sat image being taken in 2015.). See the two attached images.

Secondly, 9 months ago in July of 2015, there was an bust of a large crime ring out of Cleveland Ohio called 'Operation Goodfella' which involved salvage yards and stolen car parts. One Carmine "The Bull" Agnello was the leading suspect taken down in these raids. This is of note because Agnello was the ex-husband of the daughter of a fellow named John Gotti. Yes, that John Gotti of the Gambino Family.

Probably means nothing, I just found it interesting.
