Tesla founder Elon Musk confirmed late into the night Sunday that production on the automaker’s less-expensive Model 3 sedan will begin on time, in what’s tantamount to a bizarre attaboy for

In a string of tweets on Sunday, Musk disclosed that Model 3 passed regulatory requirements for production, and the new car will start rolling off the line later this week. A “handover party” will be held on July 28, he said, to deliver vehicles to the first 30 customers.

Ever since the Model 3 was unveiled over a year ago, Tesla has racked up an estimated 373,000 reservations for the vehicle, though the company . For Tesla to reach the goal of 500,000 vehicles in 2018, and one million annually by 2020, it needs significant buy-in from the public on the Model 3. Early on, the $35,000 all-electric sedan is going to have limited configuration options—just the color of the vehicle and the size of the wheels, .

Back in 2016, Tesla said it by the end of 2017. That always seemed like a pipe dream, and Musk’s announcement Sunday proves that was the case.

Tesla has said the initial batch of Model 3s will be used by company employees to address any kinks that may develop. It’s unclear if the 30 customers getting a car at the end of the month are Tesla employees.
