My dear, such question has been asked many times on PW but Pakistan is lacking the infrastructure for EV. I know of so many in my circle who purchased such fancy stuff for use in Pakistan and are now wondering what to do with it either due to charging stations or due to parts requirement after breakdown therefore i would advise you not to go down this path. After quite a hassle you may get your vehicle the real problems start during its use in Pakistan. You may check the weboc system for duty or a customs broker will be of much better help.
