Any changes to exterior body when comparing the "elegance" package to "sport" package? I have a 98 c230

I noticed the side trimmings in elengance models have a grey that does not match my silver body. I really like the solid color in the sport package. Here are some pics of what I'm talking about:





Anyone know how I can convert mine to look like that? Paint job? or is there actually an oem strip which I can fit on... Steve from Netherlands, I know you know!

EDIT: BTW, excuse my photoshop skills, and to the owners of those cars in the pics, I mean no disrespect to your car whatsoever, just needed a reference to show.
