Picking up my x5d at performance center in early november. Just now getting to the accessories. Trailer hitch was part of the deal but still has to be priced. I was told it will be about $550 for hitch and another $1000 for labor. Not clear if other parts are needed (cross member?)

What are others' experiences? What kind of discount (if any) was offered on the hitch and on labor? Seems odd to me to be paying labor for a car that is coming straight from assembly line.
