Unlike NZ, in the US contest winner typically pay taxes and delivery charges. However in this case that's covered by the organization.
It's US $250 x 4,000 tickets, so the organization is raising one million less the $210,000 limit. It's clever because I suspect the organization is not paying for the car up front, but from the proceeds.
Obviously they'd need to sell 530 ticket to break even.
If there was a NZ contest, I'd enter it, because I'd want the steering wheel on the right side.
If someone approached Tesla NZ, perhaps they be willing to show a model X at a mall supporting the charity. I'd bet they sell out of tickets over the Christmas period.
