Tesla's summer 2016 referral program ends today — this is your last chance to save $1,000 on a new Model S or Model X.

With the Tesla Model S 60, combined with federal tax credits that can bring the starting price of a brand-new Tesla down to $57,500! Or you can get a Model X 60D for as little as $65,500!

Tesla Model X and Tesla Model S — save ,000 on yours!

To egg on existing owners, Tesla has a unique set of incentives. Those that refer two or more customers will receive a Tesla-branded weekender bag in leather that matches their car, three referrals will get "an exclusive Tesla Owners Jacket", four referrals will receive an invitation to the Gigafactory grand opening, and five referrals will get a set of 21-inch custom forged aluminum Arachnid wheels (with tires and installation).

But there's one more thing: each qualifying referral will count as an entry for that referrer in a drawing to win a Model X P90D with Ludicrous Mode.

And then there's the nitty-gritty: referrals can be placed through 15 July 2016, only new Model S and Model X purchases count, and there are only five referrals available per code.
