Been humming and hawing about this for a while. And if I sell them, I'll probably regret it, but as of right now, I prefer my rubber all season mats. And we used the rubber mats throughout the summer too, so I didn't really miss the carpet mats.
Selling all four mats, the front ones branded with 'C43 AMG'. Came with the car, and as far as I know, original as I am the third owner of the car. They are old, but no tears or anything. Expect the usual wear and tear from an item with 11 years of age, especially on the driver's side mat.
