Sold thousands of units in China and gulf already, so should be pretty reliable.
Price is lower than Yaris and City, so that's a positive. Looks are above both yaris n City, quality from all the authentic reviews seem excellent.
Keep in mind:
There are no actual users or reviewers of the car here. @zahid.geol as you can see above is just a blind hater of new entrants in Pakistan, he's also a yaris fan boy.
For actual reviews, first watch YouTube, there's one review I already linked above.
Then, go to Alsvin group on Facebook. Actual owners of the car are there.
Then lastly and most importantly, go and test drive one vehicle on your own to form final opinion.
As for resale, a Toyota in Pakistan will always have a high resale.
