Those short sided liners are all very well but do not protect the back of the rear seat or the sides of the boot area. I bought a washable zipped liner for my S203, moved it to the S204 when I swopped. OK, the fit now is not perfect, but the front unzips over most of the back seat when I lower it, I can throw it in the washing machine if needed, and it protects the back of the rear seat and the sides of the boot area, hence the short plastic one that came with the car is in the garage and will stay there until I sell/PX the car!
