Mercedes-Benz S-Class and 2014 Audi A8- price and launch date

Friends,
My father is a successful businessman here in India itself till now we were having drives in the small car brands but, now we want to go for a bigger brand even we can say one of the higher car brands. We have decided to buy a car either of MERCEDES or AUDI. Rcently I came to know that they both are launching new models under their names namely:-
Mercedes-Benz S-Class and 2014 Audi A8 now, I want to know their price range and the features in which they differ from each other.
Please revert back soon.

See my friend it is good that you want to buy such cars. But, the truth is that they are being still not launched in India and nor we know much about the features of these cars as the companies have not leaked such information.
So, as we see the price and the features are still to come in market. Till than you have to wait.
