This has bothered me for a while, now I'm actally motivated to do something about it. I have an '06 A6 and the rubber floormats in the rear dont quite fit right; though the front ones fit fine. I've done a little reading and I guess they changed the location of the gromit for different C6 A6 models, but I don't know where to get floormats that will fit, and it is rather annoying that they only hook on to one side so don't really protect the carpet at all.

any help shall be greatly appreciated.
