Someone started a rumor that I was paying between $600 and $800 a month for my car.  People think that just because it's a BMW that the payments are higher than my mortgage.
I also had people ask me why I bought a Z3 (because there are 3 people in my family).  "Where's the baby sit?  You need to buy a minivan."
Let me start these off with, "I bought the Z3 before I got married and had a baby you f***ing idiot."
"Minivan?!  You just want to be able to laugh at me as hard as I laugh at you (don't take offense, EPJ)."
BTW, that kills me.  Everyone I know with a minivan has been pushing one on me lately.  The way I see it, if it doesn't fit in the car, I don't need to take it with me.  Some people are so materialistic.
