The grill is the same style on all SLK170s...the 32 has the same honeycomb style as your 200.
Some guys on another forum have installed the grill you are asking about and the fit is very good but some have reported weak brakets...but they got theirs on a group-purchase from an ebay seller...1/3 the price and looks like the same grill to me.
