Hi all, I "thought" I ordered the illuminated grill MB star when I built my model. In fact, I have the printout and the extra option cost. Apparently, my sales person neglected to order it when she actually did the paperwork. So, my question is, is this something that the dealer can add after market, not necessarily 3rd party, the actual part from and at a MB dealer? Or is it too late? Thanks
