No need car details and old owner details in NOC. only your dtails and sponcer details.
its in arabic. normaly the companys Admin/HR will handle this.

i purchased a car 2 week back. what i did, i made a letter from typing center(because i don't have HR/Admin Dept.) and give to my sponcer after that i kept in my hand.
later i got a car then i use that leter for ownership transfer.
