Refer 10 friends and get free Tesla Model X SUV

Update, July 31:
In Australia, Tesla is offering a version of the referral program between now and October 31. Any purchase of a Model S through the owner's link will earn the buyer a $1500 discount and the existing owner – who referred the new customer – a $1500 credit to go towards any future purchase, service charge or accessory cost.

Tesla is imposing on each customer a ceiling of 10 discounts, each worth $1500. Any owner referring up to five friends ordering a Model S will receive an invitation for himself or herself and a guest to attend the grand opening of Tesla's Gigafactory in Nevada. If they refer 10 new customers to Tesla, they are entitled to purchase a Founder Series Model X, which is not available to the buying public, with all options free of charge. According to Tesla the options are worth $25,000 retail. The first person to reach 10 referrals in the Asia/Pacific region will win the car at no cost to themselves.

Tesla is primed to introduce pioneering (and lucrative) customer referral scheme for its US customers to boost sales of its new Model X SUV through word of mouth.

The incentive bonus, that sounds similar to a pyramid scheme, was revealed by US magazine Car and Driver.

When current owners of the Model S refer a friend they receive a (US) $1000 credit off the purchase price of their next car, while the friend also gets $1000 off the price of the car that’s been recommended.

If you recommend five friends you earn a tour of the Tesla factory but convince 10 mates and you get to buy a special-edition Founder's Series Model X at a $20,000 discount.

Even better, the first person to recommend 10 friends in their US State gets a top-of-the-range Model X for free.

The new incentive scheme, thought to be a trial, will run until 31 October 2015.
