Impressive list. This car still remains a favorite of many people, inclusive of myself, and I'd gladly take it again, if offered zero-metered, no doubts!
Sadly, most people around will not understand some of the technical terms above, yet that's quite an arsenal there for lovers of this model.
I searched through the whole list, but apart from lower ball joints, I found nothing specific for this particular model's "ACHILLES heel": The Suspension!!!
Did I oversee anything, or what?
The suspension work offered by most people (Kharadia's) in Rwp/Isl normally is a 2-3 months lasting love affair only and then back to the workshop!
I have a strong feeling that this particular model's rear suspension cannot take the load of the CNG cylinder for prolonged periods and drives on uneven roads (90% of drive in Pakistan).
The best way out is probably driving it on petrol only, as I was told this by Honda service outlet in Islamabad: "Sir, remove this bomb in your trunk, and you'll not be visiting the Kharadia for some 3-5 years"!!
I feel people having this model car would be more interested in seeing more suspension parts to your list, lest I oversaw it, somehow, kindly ignore, if so!
Best of luck.
