exactly my point. and nevertheless if you install it now and keep the car until it's completely undrivable ever again, or if you sell it. the next owner or yourself will have to deal with that problem. if you sell, and there is a problem with the glass later, it will all be dropped on your lap.
just be careful where you go to ge the work done. there are so many safety regs with glass, and alot of people shortcut. do your research.
