Silicon Valley is an interesting place when it comes to cars. As somebody posted earlier, Tesla is definitely the "it" car. And at the last company I was at, one of the founders who's worth many tens of millions did extensive research and even made a spreadsheet when he was ready to buy his next car, and he got a Volt.
As a car guy who loves sports car and exotics, I just shook my head.
Unless somebody is in sales, marketing, or is an exec, I think it's actually discouraged to drive a high-end or flashy car. The last company I worked at minted many multi-millionaires upon their IPO and I don't recall one person (seriously, not one) who got what I'd consider an ultra high-end car like a Ferrari, Lamborghini, Bentley, etc.
Before I started my new job, a friend of mine who was already there cautioned me against driving the new car I'd bought into work because the CEO and co-founded wasn't in to flashy cars.
Screw him. I worked hard for what I have, I can afford it, it's not eating into my financial reserves at all, it's a much nicer daily driver for the horrible Highway 101 commute than my other car which is a beater, it's my life, and I'm driving it. If he doesn't like it, he can shut his pie hole or fire me. Either works for me.
Car culture here in northern CA is just weird, bordering on nonexistant.
