Paint does not like to stick to chrome. As such, a paint job on chrome may not last long and never look quite right. A grill takes just as much, if not more, abuse than the door handles. Every stone, bug, etc coming at the car hits it, it gets massive heat soak from the radiator, plus it is supposed to look good 24/7...not an easy order. If you want to dress up the front of your W202, I would very seriously consider swapping in the grill from a W210 car. As far as I know they are a very easy swap. If you are interested fill out a PartsShop inquiry.

Hope this helps...Lee
