Actually, I bought the smart velor and rubber mats along with the rear boot tray from
www.Bald.de via ebay. They are all happy to be in my smartie. Well the velor ones are still in the bag in the house but come Summer, I'll switch out the rubber ones. By the way, the boot tray is excellent for keeping your boot area nice and tidy. Also, it's cool that you can just pull it out as it slides out very easily onto the rear tailgate when it's open.
