When I see a super-expensive car like a Ferrari, I don't tend to think that person is rich, I tend to think that person is missing $300,000 from their bank account, or they have a huge payment for a car that doesn't actually get them anywhere. At the end of the day, I really only care what one person think about me. That person is my wife. She keeps me grounded and helps me keep my priorities in line. Why would I buy a $300,000 car to impress people I don't know? I'd rather have that money to help secure a future for my family.
Those are just a snippet of my simplified thoughts though. :)
