I'm trying to decide on all weather mats for front/rear and cargo area for 2007 Prius. I appreciate your feedback. I've ruled out exactmats. Do the Toyota genuine all weather mats come in grey? I've only seem to find them in black. Any pros/cons of the weathertech and carbox II cargo mats/liners ? Is the weathertech lighter in weight? Do they fit the periphery of the cargo area with the rear seat up? Are there pictures anywhere for either installed in a Prius 2007? THANK YOU!
