Thank you very much Bhai for your appreciation ...
The motors for the retractable mirrors are made by MATCO .. the same vendor which manufacturers the -non-retracting joints for side mirrors. When I bought the pair, they looked totally new, however, the packing was not available with the shopkeeper. It is possible that they might have come off some imported car. Just my suspicion, otherwise, the shopkeeper said they were new. I also checked the switch, which did not show any scratches on its contact terminals, so probably it was new.
The shopkeeper demanded 9000 for the motorized joints, switch, wiring and the labour cost. I paid him 8500. A fellow PakWheeler mentioned the price of 6500 in this thread for Peshawar, so you may explore that option if convenient to you.
The side mirrors are folded and unfolded manually using the switch. I have not experienced but the installer said that the mirrors will move inwards in case of impact. However, he said that the mirrors should not be moved by hand as a matter of routine.
Have a nice day
