Yes, I understand there are some features, like heated seats that would not be useful in Sri Lanka. But overall running, general use, is there a significant difference? I think "bigger radiators, harder suspension etc." is just a con. For example, take Radiators. In the US, one can go from bitter winters of New York to scorching heat of Texas. And Texas itself, Dallas is cold, compared to Galveston. So BMW makes a different version for New York vs Texas, and Dallas Texas BMW is different to Galveston Texas BMW? Not.
I owned a Domestic Japanese X trail and it was not significantly different to A*W imported X Trail Except my X Trail had factory HID, GPS etc.
