Brin, a friend of Musk and an early Tesla investor, has previously owned a Model S.
The first new Teslas are always nearly impossible to obtain.
Before the Model S came out, Tesla board member Steve Jurvetson carried a blank check in his wallet after spotting details about the upcoming car in a hefty Tesla information packet. Before the next board meeting started, he whipped out the check, filled out the price, and tossed it to Musk, he told Patrick May of the Mercury News in 2010.
Jurvetson managed to snag a Model X on Tuesday night, too.
The eagerly-awaited Model X seats seven (while also capable of carrying 5,000 pounds of cargo), and can hit 60 MPH in 3.2 seconds when in "Ludicrous Mode." The car, which starts at $132,000, is on sale now, but the 25,000 pre-orders mean that even if you order one today, you'll have to wait eight to 12 months before you'll get it.
