@Ashfaq bhai,
Thats what i said/meant!
This is part of the car's nomenclature!
All automakers do this to keep difference in the same car according to the regions they are marketed in!
A good example is Suzuki Verona/Daewoo Nubira/Chevy Epica!
Another would be Mitsubishi Pajero/Montero/Shogun!
They are all the same, but have different names in different regions and have minor exterior/interior differences!
I bet you already know all of this...
