The car is a 100% JDM import, I have the documents to prove it.
Yes, this car does not have a sunroof. The sunroof and the rear windshield wiper were all optional equipment back then (I also almost everything about JDM Civics). Even ABS and airbags were optional back then
The bumper came with it when it came to Pakistan. Lots of people (I would not like to mention their names) asked me to sell it to them through PakWheels. The bumper came with it, as it is.
I hope I answered all your questions.
