Nishat Hyundai hasn't launched any car as of now. I don't think they r famous for high prices.
As for Hyundai Kia group, they have captured the market in middle east and north America due to their pricing strategy. They always price their cars low as compared to Japanese manufacturers. Though I m not sure about the Chinese though, they might be even cheaper.
As far as 800cc is concerned, Nishat group has expressed interest in launching hatchbacks and hybrids in their press statements. If they want to, I think they can figure out a way to bring the 800cc engine in Pakistan. But that might be too much wishful thinking on my part.
