I will be purchasing a Black 2013 Limited and wanted to do the same. The research that I have done has led me to think that you could have a dealer/automotive shop paint your grill a desired cover or (my thought) you could get some primed grill inserts from ebay (ebay 2011-2014 ford edge grill) and then either plastidip w/glossifier or have a dealer paint those and then I will attach. Not sure if either of these are a good idea or what the overall cost would be (welcome to suggestions).
I think I am going to keep the wheels as-is. I kinda like the chrome look for the time being.
