It was indeed properly maintained and atleast never abused since I bought it. I ran it for almost 20000 KM. Yes, Cultus is gone. Well, yes, it's a hassle to upgrade but it is what it is now. That's exactly why I am preferring a Margalla with a weaker engine. Overhauling will make sure that the engine should run atleast 30K KMs.
JazakALLAH brother. Han, I will not only look for Margalla but Baleno and Liana as well. Btw, Baleno in Karachi in top notch condition is easily available for 4.75-5 Max and Liana goes all the way from 5 to 8-8 (depending on the model). Btw is JXR/JXL variant better than GLi, GTI etc.
JazakALLAH all for helping me on this.
