Last I heard, BWMs are not cheap.
They can be cheap and they can be affordable and they can be expensive. It all depends. I think mine's worth about as much as a new Honda Civic.
Maybe the parenting-thing would have worked out better if dad had worked together with his son to bring an old project BMW back to life than flying off to photograph women's butts and using the money to buy his precious little snowflake a new BMW did.
