I realize this is an old thread.. so I apologize for waking it back up.
My girlfriend took delivery of her 535i last September at the PDC, and when we got home in California to wash it - water didn't bead on the car at all. Which tells me that there wasn't any wax on the car at all. I'm guessing they don't wax the car unless it's necessary?
