Well, as far as I know following are the vendors:
- Haroon Autos (Diljan Plaza)
- Nawaz Tyres (University Road Near GAP CNG)
The guy at Serial 1 mostly deals with aftermarket accessories as well as OEM parts (selective). Though he might have stuff like projection lights etc yet I am apprehensive about him selling body kits.
Secondly the guy at Serial 2, in addition to selling tyres/alloy rims also designs/manufactures body kits. He's got an album for that plus you can take your own designs and ideas to him.
My brotherly advice is to reach out to Isb/Rwp. The issue is that there is more variety, quality to choose from according to your taste and needs. I may be wrong, but Peshawar is a better option for parts/engines/mechanical etc. Just remember, vendors ARE GOING TO RIP YOU OFF to some extent one way or the other. If they give you projection lights at a bargain price, rest assured they will recover their profit margin in the spoiler and airpress they will sell you.
