I used this forum for fitment on new wheels for my eclass and it went perfect. I am now looking for a friend for xmas. She has a 2010 C300 4MATIC. I want to get her 20 inch setup in all black. I am really struggling to find anything that would fit. Not going HRE or anything crazy, and obviously she is not a sporting driving that needs to worry about unsprung weight and things. Just a cosmetic change for her, whereas I was looking to go up in diameter and drop weight. Any specific wheels that anyone can think of that would fit? Thanks so much in advance... any help will be greatly appreciated.
