Maruti Suzuki WagonR v/s Maruti suzuki WagonR STINGRAY.

Hi friends,
Recently I planned to buy "Maruti Suzuki WagonR" but the has launched the facelift version of the same as "Stingray" so, I got confused between both of them that which one is better. Oviously the new version would be having nnew and better features but, than also I want to know that how they both are differ from each other i.e what are the basis of differenciation between them?
Any descriptive information would be really appriciated. Thanks in advance.

I don't know that maruti suzuki Wagon R stringray has launched or not. But if it has launched then it will be clear that it must have some new features and specifications as compare over maruti suzuki wagon R. So it's obvious that maruti suzuki wagon R Stingray will be the best among these two.
