An early Tesla investor wants to offload his Silicon Valley mansion for $40 million - take a look inside

Tesla wouldn't be the triumphant car maker it is today without Alan Salzman, a well-known venture capitalist who made an early bet on Elon Musk's startup before it had a product.

Salzman owned about 9% of Tesla for a time. He sold a fraction of his shares when the company went public in 2010, and still owns nearly seven million shares worth $2.3 billion. 

Salzman, the 63-year-old cofounder of VantagePoint Capital Partners, has the eye-popping mansion to prove his wealth. 200 Polhemus Avenue is a six-bedroom, nine-bath estate in Atherton, California, complete with an in-house spa, library, movie theater, and golf course.

The house went on the market for $39.75 million in March 2017. There have been no takers yet, which means the sprawling estate in the country's third most expensive zip code could be all yours, if you have the millions to spare. Take a look inside.
