Respected ahsen_rg bhai,
First of all accept my apologies for replying to your quesry so very late. If, by now, you haven't purchased a Smart, the final price for the smart would be Rs 8,75,000.
As for a 2001 XE,CNG, it should be some where in between Rs 6.5K to 6.75K.
Awaiting your kind response.
Regards
