I purchased the rubber mats and whoa, yeah, the plastic screws actually poke into the carpet. But you don't make a whole all the way through the car. The most surprising thing about the smart to me is that every accessory seems to require new holes in the car! On other cars I've had there are already hooks or pegs for mats, cargo covers, etc., so no new holes are needed. But in the end, it's just a psychological thing to get over. No problems with doing it, and you would really have to look to find the holes when you remove the mat.
