Have them alone in the Renault Clio (Bj. 2007) mounted 5 months ago, almost any problem. Pay attention before ordering that you can lift the rear bench seat! The guide is full of well-described. Looks great chic and tidy. Since I only have a three-door, I had a hole in the reference cut (so you can find the lever to fold the seat) was not a problem and fraying absolutely not. On the back seat, I had a seam open, so that you can buckle up, and no further problems. Keep eye on the prize, 40 top! ;)
