For the vinyl floor liner, I had not found any posts on here where this had been done and couldn't find anywhere online that offered a vinyl carpet replacement for 4th gens......at first glance. I called Auto Custom Carpets (accmats.com) to see if they could be made as a special order since they were not offered in the product list for the vehicle. The lady I spoke to advised they were listed under "other" products, since the vehicle is an SUV and the material only covered the passenger area (not the cargo area). They have since updated their website to include vinyl as an option.
I have to say I was happy to find a manufactured alternative to carpet and this is some really thick and durable stuff, but I was a little disappointed in the level of contour stamped into the liner. The location of the impressions in the vinyl matched the floorpan well, but the depth was just not there. Nonetheless, it does its job and I'm happy with it overall.
