14km/l is very good average for 1500cc car in Pak. (because probax has CVT transmissions hence good fuel economy).
But don’t remove it. Let it be there as it is.
4wd automatic turns on and that’s main issue.
Well, can you find some switch or button to keep it off ? this button is available in many jeeps specially older models. So I guess there must be some switch or button for it too. But never go to remove it.
As far as re-sale is concern. Removing 4wd will bring down cars value when people will know that its original versions comes with 4wd.
