I assume you are thinking of rear pop out windows - mine are fixed as it was a "yugoslavia spec" car - so little to no additional luxury in it. I believe all US spec Mantas were Luxury model to begin with so they all had them - all export Mantas were L (luxus) coded.. Here they were in cheap option cars and I think GTE version. I will probably swap them out for the vented ones since it helps significantly during summer. Had them on my e21 BMW and were great. I heard that more sport oriented owners are now looking for fixed windows but I do not know the market for these.
