I had to have my wind screen changed 3 times (2 aftermarket and 1 OEM screen) a few years ago on my BMW when I noticed that the aftermarket screens had very noticeable distortion a few inches up from the bottom of the screen. Easy to see when looking at road markings when driving. In the end they put in the OEM screen which was perfect.

Might be less of a problem on the L322 due to a steeper angle on the screen. Tom
