1. DIAMONDS - this car has a diamond grille, a diamond license plate and diamond covered wheels. Talk about your waste of money. Not as bling as the full diamond covered Mercedes SL(LINK), but pretty close.
2. Style - if you have all those diamonds to cover teh grille and the license plate in diamonds,, why did you only cover half the spokes on the wheels? Of course they could have fallen off, while they were driving(and isn't that an interesting mental picture), but then again the pattern is too universal for this. Actually if you look at the license plate, a number of diamonds do seem to be missing.
3. Raises a question - if you have all that money for diamonds, why are you doing this to a "crappy" BMW M6, and not a Bugatti Veyron?
