Unfortunately the ad campaign was not a particularly big success, in part because so many people found it so convincing as the ad itself gave no indication at any point (whether in the pamphlet or on the various wed sites it led you to) that the whole charade was nothing more than one big car commercial.
As for myself, at age eighteen I had read alot of 'strange but true' books on various topics (UFOs, ghosts, bigfoot, etc...) and could smell a hoax the moment I read the opening of the pamphlet which quoted Aristotle about being open minded. Nevertheless, I still found the whole thing quite fascinating.
Today the ‘Mini Cooper Robot Myth’ remains a fascinating footnote in the long history of humankind’s relationship with mythical mechanical men.
