“It's time to bring the Model S and X programs to an end with an honorable discharge,” Musk said. “If you are interested in buying a Model S and X, now would be the time to order it because we expect to wind down S and X production next quarter." The first customer deliveries of the Model S began in June 2012, followed by the Model X in September 2015. Tesla will continue to support current Model S and Model X owners with any servicing needs. "We'll obviously continue to support the Model S and X programs for as long as people have the vehicles,” Musk said.
