The nearly vertical windshield takes rock hits and is a frequent replacement item; owners note a plain unit can be swapped cheaply, but heated windshields (with embedded coils) or antenna-integrated glass run into the thousands. Replacing heated glass with plain glass also disables the heated-window and rear-defrost functions, a detail buyers probe.
