hi, I am no very sure, but I heard that you can buy any mercedes S-class, or E-class ( muti chrome strips grills ) and cut the sides a little bit to make it fit. That is what I heard from a person from KLEMMAN.
Their website hads the grill on sale http://www.kleemann.dk/default_old.htm
Also you can try couple other places for lower prices
like bekkers import. www.bekkersimports.com
hope this help.
