I replied to your context of CBU, Corolla being CBU is a null case because they are manufacturing it in PK and no need for CBU.
Why do you compare abused 3.5 or r grade car with a 5 or 5A grade car. If you import one yourself or from a trusted dealer and there are many you can get an exceptional Aqua in 2 to 2.1 million the price of PIAZ auto. I am not talking about the ones you get for 1.5 to 1.7 million.
As for reliability, Aqua in good condition and proper record is 100% more reliable as it has support of 1000's of importer and user base to back it of. As for PIAZ on 200 units were imported i can still find many units at all dealershits, so that means safely 150 units sold in pakistan and you are talking about support from SHITZUKI who cannot fix the issue with breaking windscreen in Swift a car they have been assmbeling for more than half a decade.
You continue to live in your fantasy world of having the best sedan currently in Pakistani market. I still say not a bad car but insanely stupid price.
One question of this car was priced 3.5million PKR would you still buy it?
For any sane person the answer is NO, so that means no matter how good it has to be reasonably prices.
As for thai build quality, it is no Japan, they have assembly plant and QC control. QC is missing in SHITZUKI Pakistan. but QC is some what better at Honda and Toyota.
