hi, I had a cracked windscreen(IS 200) a few years ago,luckily I had read a lot on this forum regarding problems with non Lexus labelled windscreens not fitting properly,letting water in etc. Consequently when I first contacted my insurer they were a bit reluctant to accept my request for a Lexus labelled windscreen,however after refusing to accept anything else and insisting that's what I wanted,a few days later they agreed to my request. I then had to wait 2 weeks and equally had to phone auto glass to inform them of my request and make sure they didn't bring anything else.
