I have had wet okole covers in my truck now for over 170k. They have been very good. I will have to admit that I have not kept them clean and they are showing it but I have definitely got my moneys worth with them and will buy them again in a heartbeat when the time comes. My wife liked them so much we got some for her 4 runner. When we sold it we transferred them to the new 4 runner. Seats are a bit different but they still fit very well. Hers not seeing the abuse that mine have still look great (though hers only have about 100k of seat time on them). I purchased the covers so I wouldnt have to worry about ruining the originals as I know I abuse seat material and they have certainly kept the originals in like new condition. Only drawback if you want to call it that is they are waterproof you spill a drink in your lap the seat wont soak it up your pants will though.
