New Guy here, 1st post. Recently purchased a 2009 V8 with R-tronic. I'm spending some time combing through it and I'm a stickler for details. First thing I noticed is that I'm missing one of the floor mat retainers. This is the round piece with nub that mat snaps down to. I have the Limestone Grey interior with the light mats. I've done some searching but have not been able to find these anywhere. Any suggestions?
