Here are two photos of my mundane mod showing the
much improved coverage area compared to the stock rear mat:
I cut notches with a pair of tin snips so
the mats would fit between the front seat tracks.
Here is a photo showing one of the mats in place:
I bought two sets because the driver's side front mat has the anchor grommet.
Now I have two spare driver's mats to put into service as that mat shows wear.
A set of front mats is $35, or $70 for two sets.
I'm a member of the Chrysler 300M Enthusiasts Club
and my dealer joined the Club's discount program,
so I got 10% off, and both sets of mats only cost me $63.
That $7 savings gets me back half my cost of membership already,
and I haven't even gone in for my 15,000 mile service yet!
