Stuart G from Roanoke, VA said, "Having owned these mats for a few weeks has allowed me to really notice their more subtle qualities. One thing is that because they are heavy they make my car even quieter than before. also they seem to be hand cut so the fit is great, even better than the factory mats. Break the carpet addiction and go with heavy rubber.js"
