As I mentioned, I've read, and heard several reviews of those who tried changing the transmission only. In fact, I met some in person too. All of them noticed a significant reduction not only in mileage but also in performance. Also, K6A engine produce 63NM of torque at 3500–4000 rpm, considerably more than that of Mehran, i.e, 59NM @ 3000. Thus, not under-powering the car. And To be frank, I am tired of explaining and teaching the clutch and gear combination/working. I want a car which ladies can also drive easily, & the deterioration during the learning process ought to be bearable. A scratch or a dent on Mehran won't cost as much as on a Hustler or any other like it.
As far as I am concerned, I am fine with this car. The Euro-2 - EFI engine is good with fuel average, and AC performance is reasonable. At least way better than its predecessor carburetor F8B one. Moreover, its "power steering" helped me increase my biceps size.
