I think it would be "cool" if Tesla, once they get your deposit, send you something like a "credit card" looking trinket ... that shows your name and number on it.
So you can show you are a member of our "group".
Not showing off exactly, but it would be a nice tangible ... like the airlines issue a frequent flyer card.
After all, we are "ambassadors" to help others move to electric.
I have a neighbour here who is more green than me, and he's buying a Prius in a few months. So I have to convince him to at least, go Leaf first, then Tesla when available. Think I saw his brain mulling it over last night ... but his daily commute is 35 miles. Borderline?
