Car is in 59715, Montana. Need all the carpeting for the car. Currently has cognac interior so some sort of tan/brown/black is preferred. Also need the insulation mats. Let me know!

There is a vendor on eBay from northern Europe who sells carpet kits for $360 when you include shipping. The name is Ricambia or something like that. I always find it by just searching for w115 carpet kit. For some reason, if you search for w114 carpet kit, you only will find their coupe kits.

As far as I can tell, this is the cheapest high quality carpet kit for the w114/115. But it (and others as well) doesn't include the foam or have snaps on the carpet. I recall the vendor of the foam is given somewhere on pp, but they don't ship to US.

Hopefully someone here can help you, but my experience is that even good looking used carpet will not survive a transplant from one car to the next.
