I have an S-Line Avant in the dark grey colour - car looks really nice, but having come from a black line C7 I think it looks a bit rubbish not having the back windows tinted. From a practical point of view too, having 3 young children, its also annoying in that I have to use blinds etc for them.

What are people's thoughts on aftermarket tint - I would just be looking for a factory style look doing the rear door windows and rear screen. Not up to date with such things, so no idea how reliable it would be etc,
