I worked at a pizza place in highschool and one of our delivery drivers was an elderly guy who drove your typical delivery driver beat up old Honda Civic type car. He was a super nice guy, but never talked much about himself. Then one day he shows up to work in a Maserati because apparently his Civic wouldn't start. Turns out he was a crew member with freaking Jacques Cousteau and was very wealthy. He just delivered pizza for something to do and because he liked meeting new people.
He eventually sold the Maserati to one of my coworkers for a couple of thousand of dollars because it needed a new fuel pump and he didn't feel like dealing with it. Yet, he kept that sun bleached Civic for as long as I worked there.
I went to graduate school with a guy who turned out to be from a super-wealthy family but we never suspected because he drove an honest-to-god fucking Yugo. I rode in it once and pulled the window crank off the door before he had a chance to stop me. He drove the Yugo because he wanted to fit in with us poors - we should have suspected something was up because not even the poorest of the poor graduate students drove Yugos. He finally blew his cover when the Yugo died and he had to come to school in his other car, a brand-new Range Rover.
