ive heard about this problem, and apparently through australian compliance, they put a bar in the doors which effect the rollers or something, like gets in the way, or creates less space or something... eh its what i have heard, and when i bought my car, the lines on the windows werent showing, i am the first owner in aus and had it all complied.... but now after having my car about 5 months in aus, it is showing, so its coheesive. im not saying i know for sure this is the problem, its just what ive heard.
