Tesla Motors has a (fairly ongoing) campaign to sell its cars. Current owners (and maybe those with orders in) receive a link to share with anyone interested in owning a Tesla. People using the link will each save $1,000 on the next car ordered.
If any fans of Tesla in Japan decide to take the plunge, please use this link to start your adventure. My Model S P85+ is the most awesome car I've ever owned or driven. If you ever try a Tesla out, I think you will agree.
[EDIT] I bumped this post up to the top because I just noticed I have one referral (I didn't even know where to look). Anyway, thanks for choosing Tesla.
