Your bumper can ellicit such compliments!!!!
See the thing is .. that with the best chrome work, if the basic bumper has dents, despite them being straightened, will look sloppy. That is the plain truth! But if you are looking for a final look of the car with bumpers to DIE FORthen "new" is the only way to go. It all depends how deep your pockets are. Have a read of this blog:
Stainless bumpers for W111 from PTT Vietnam - Benzworld.org - Mercedes-Benz Discussion Forum

Getting bumpers imported into Pakistan can be done. Heck Nasir Sheikh got the whole engine from US for the camper that he is restoring. So as I said, how deep are your pockets?
Cheers
