EV is without a doubt future of automobiles, but in Pakistan, it will take a while to adopt and get used to in terms of consumer market.
However, even if you opt out for EV, in your budget for now, it will not be possible for you to get pure EV vehicle (other than Prius Plug-in hybrid I guess), for that, you have to increase your budget.
Personally, not a big fan of the ridiculous decision by Indus motors of launching Corolla X, my honest suggestion to you will be to get a low mileage well maintained Grande of 2019 or 2020 model and save yourself some money.
The rest is your choice.
I hope it helps.
