Hi, this may be a dumb question but is there any way to put on curtains on a door with no window frame? i may get an ES300 and, of course like any car enthusist, i'm making a wish list of mods for it. since its a 3rd gen it does not have window frames on the doors. can curtians be possible to install on an ES? i've been pondering on how it can be installed but the only thing i can come up with is only the rears can be installed but it would only be for show and not be able to use them. does anyone have any ideas or is it pretty much impossible? thanks in advance.
