Came across this thread while searching for something else.
The Carbons and Steels could hardly have been left-overs from Poland, since that is a LHD country.
The limited editions of the Carbon and Steel variants were planned to tap the pulse of the market with regard to a 3 Door.
Sadly, India still believes in the need for 4 doors since even if not always, most Indians want to transport self, wife and kids, Mama, Papa and Chacha, and will not buy a 3 door by choice as a first (or only) car!!
