Sir Cl 9 is a bullet proof machine, there is no question of any breakups or faults at all.
I have owned one (24 TL version), no local car can match its performance, even a 6.8M 0 meter Camry and Accord (Thailand) seems a big ugly bull in front of it, its a pure driver's car.
My only reservation was that it needs Shell HI Octane, nothing less (that was the only reason of selling it).
I would love to recommend you a BMW E46 316i/318i or even a Mercedes W203 C160/C180 (not the Kompressor), but you cannot take good care of it and they can be both heavy on pocket, if proper roads, technicians and fuel is not there.
You can get them all in good condition within your budget (in Karachi) .
So in the end I recommend you an Altis Cruisetronic SR in your favourite color, it is leagues behind the cars mentioned above but its a decent car and you cannot go wrong with your investment.
