I read in one of the threads that the PP has acoustic window glass. What is this and how does it differ from standard window glass?

The touring and elite have acoustic glass. It’s basically a double layer of glass with a membrane in between, sort of like the windshield. If you have one of these models put the window down a little be and feel the top edge you can feel the double layer

Thanks for the info. I'll check it out.
