@autophile,
i have got unusual question for you 
i am going through the same delima you must have gone through just before making the mind of going for 1.6 variant.
i am confused between 1.6 and 1.8 variant. Taking about 1.8 i think grandee is the way to go and on 1.6 we have only option.
Therefore Considering yourself in my shoes...what choice would u make.... considering the fact that its appx 300k difference in price (one time) and then there are certain recurring costs involved (mileage, token etc etc). On the other hand.. yes.. there are certain value add-ons like CVT, sunroof extra padding on doors i guess and of course more engine power and the joy/ feeling of driving top of the line varient. 
i hope you can understand my situation and would do your best to help me make a better decision.
Thanks.
