When I bought my Audi TT 225 quattro, the dealer left the front bumper alone. I asked them about it before delivery, my salesman said they never drilled holes on customers cars unless they were told to do so.
I guess it just depends on the state's law. In Texas, you have to display a front plate, but it does not have to be attached to the bumper. A lot of foks here just run without one, me included.
