In my city a ML 500 chrome grill, I bought 2 for two customers already... and they are just under $400 CAnadian that is equivalent to $236 US.. that is straight off the MB Parts Department.. Maybe you should ask them how much a ML55 grill cost?? Or go to another mercedes dealership and get a quote from them.. The chrome grill is so easy to install, 10 phillips screw, after you take them out turn it vertical and comes out with no effort.
