Warren Buffet generally drives (or more accurately, is driven in) a Lincoln Towncar. In fact, he just donated one to a charity that was sold on Ebay for about $70K. So nothing special there.
A family friend who founded NTAP a decade ago (think he might have been a billionaire for a few days during the height of the tech bubble) drives a Toyota Prius.
Some wealthy people just aren’t “car guys”. Jay Leno owns literally dozens of cars, whereas I understand Tiger Woods actually drives the Buicks he endorses, which (as a car guy) just blows my mind.
