I bought these mats new from the Mercedes-Benz dealership when I purchased the car from them in July 2010.  These mats have never been installed and never stepped on.  I just noticed when I laid them out that there appears to be some sort of flaw in the passenger side front mat, an irregular cut or something that resembles a slight crescent grooved into the carpet.  The last two photos are an attempt to show this defect.  If you have any questions whatsoever, please let me know.  If you'd like additional photos, I'm more than happy to do that as well.  Seller does NOT ship out side the contiguous United States.
