You’re quite wrong..
First, civic and special Corolla are hot market cars. Even if new ones now cost above 4 million.
Why?
The alternatives are even more expensive. Sportage, Tucson, etc. that new toy Elantra has already crossed Corolla 

And
Cars specially market cars like Corolla and civic sell very fast, specially in Islamabad and after that Lahore.
Entire kpk also jumps at ISB cars and then LHR cars.
Maybe Karachi market is slow. Or you were demanding a lot, usually Khi number cars are much cheaper than ISB n LHR cars.
