Front bumper can easily be adjusted through a denter - maximum PKR500 - depends on your generosity though, can exceed.
Suitability and personal preference is key to choosing the right rims for your CL9. If I were you I'd just go for the OEM Euro or OEM Luxury-package rims instead of the fake-chinese knock-offs being sold in the market. OEM's might set you back PKR50,000-70,000 just rims - depending on availability, condition and sellers-mood.
