I would like to replace the drivers window on my cooper s , as it is scratched from going up & down . Are all the windows the same, or are they tinted different colours for model / car colour etc ? Thinking I could probably pick one up at a breakers ?

Also it is very scratched , is that normal ? The passengers one has a bit as well . Car had tints when I got it on the front, maybe they pushed the window along the outer edge baing a bit thicker ?

The driver side door window on our MCS JCW has vertical scores as well. I tried cleaning behind the window seal as I thought there might be grit or something trapped in there but I didn't find any. Is this a common problem?
