Welcome to the forum.
The car pictured could be a W221 chassis / model (i am no expert on later model Mercedes though.
Please click 'Forums' on the toolbar top left, and scroll down the drop down to W221.
Daimler Benz made different versions / spec of same model cars for different parts of the world.
In order to get relevant to your car advice on an international forum like bezworld, location (at least country or state) can be important.
Clicking 'User CP' will let you fill out your profile with car mod and location.
You can also search the forum archives with vB
search, which can be a bit cumbersome until you know your way around.
The 'google special search box' top right might be easier.
I'll copy your thread to the W221 and close this one.
