Just an FYI for anyone using the REM trunk mats. Don't use any kind of harsh cleaner on it! I bought something in the swap meet at a show, and got grease or something on the one in my Challenger. Wiped it up when I got home, and then used a rag with diluted purple stuff to get the oily film off. Well.....it came off, along with the gray plaid pattern! I guess that's what I get for using the trunk to actually haul stuff!!!
