I can tell you that where I live, most people drive cars valued between 50k and 100k. I'd say the most popular car in my neighborhood is a BMW 5 series. Lexus LX470s are popular too.
When you're successful enough, you don't need a car to make you look successful.
And that applies to you?!? LOL I bet you live off of your paycheck.
And NW, actually. Buffett has a mercedes along with his Cougar. Don't know if he has the cougar anymore though. He doesn't care about his cars because he never drives - and same goes with most of the people you mentioned.
