Well, he did say he has a 1.9 Z3, where as his friend's family has all those expensive cars. There are a lot of wealthy people out there, although some might not be too comfortable disclosing their level of wealth, but it doesn't stop their friends from telling the world about it. One of my close friends likes to mention that fact that I have a Z3 in conversations with others, however, I myself is not too comfortable bringing it up every other breath, it'd only makes me sound like a pompous ass. I think most of us do it once in a while; we tend to like to say things that would put us in the spotlight.
