I replaced mine with ACCMats stuff. I think that is all you can get, most places just resell ACC Mats stuff.
The carpet is crap. It doesn't have the insulation it needs, it has the wrong texture, wrong color, and basically looks cheap. It looks more like trunk carpet. It doesn't fit right either, I fooled with it forever, and it won't lay smooth. I can't get ride of the wrinkles.
Plus you have to be very careful cutting the holes for the shifter, ebrake, seat bolts etc.
The plus side is it is very light, it weighs about 1/4 what the OEM carpet weighs.
My advise - find a clean carpet at a junkyard. You will have to keep checking back and pull it as soon as they get a vehicle, before it gets rained on. I have seen quite a few sets in nice clean base late model 3.8L cars that got a good front end hit or something.
