Hi all. When I purchased my W204 coupe there was damage to one of the interior parts and it's been bugging me ever since. Not to sure what the part is called but it's in the middle of the rear seats. Its the rubbery plastic part that surrounds the cup holders in the rear seat. I was just wondering if anyone knows how much this will cost me to fix and where I can get the part from? I'm worried I'll have to change the entire back seats just for this one part. I've attached a picture of the area for reference. Any help on this would be much appreciated.
