"You and anyone using your referral link to buy a Tesla will receive 1.500 free Supercharger km!
Each referral now also gives you a chance to win a Founders Series Model Y or Roadster supercar! Tesla owners who already have free Supercharging get two chances to win.
Tesla cars have the lowest overall probability of injury according to US government NCAP testing, so every referral helps reduce your friend’s chances of injury or death.
Thank you for helping accelerate the world's transition to sustainable energy."
