Ya know, I am going to follow this (interesting) thread and hopefully, no one will mind if I chime in here and there.
At this moment, I would like to comment on TJ's post:
TJ has very accurately pointed out how easy this car could have been created and also how easy it would have been to acquire the "paper" shown along with this car.
I like his "urban legends" comment. That reminds me of all the stories of the cars that came out of California museums. Must be thousands of car museums for that many cars to have been stored out there
