It may be interesting to see Elon Musk promoting both the manufacturing through to promoting of the car on stage in a celebrity, iconic way.
Elon Musk appears to give the Tesla lithium powered cars not just a presence, but also as a futuristic, evolving journey.
I am not aware of any other car manufactures that do this, but instead appear to just leave the car as a product/image for the advertising industry to promote.
As oppose to Elon Musk who appears to spearhead the Tesla marketing himself and give a more personalised view of the trials and tribulations of putting these cars together.
The above activity may be also seen as a major plus for Galaxy/lithium sector from a marketing point of view.
