My Boxster only had a mesh insert on the driver's side when I bought it. The mystery of what happened to the passenger side insert was solved when I found its mangled remains at the bottom of the compartment that the convertible top folds into!
Although my Boxster had the mounting hardware installed it did not come with a lexan wind blocker. The used one I bought on e-Bay rattled so much that I rarely used it until I replaced the latches. Now it doesn't rattle at all.
