buddy mine is Automatic!! it was CNGed, wen i bought it!! didnt check the mileage, as i get that thingy out of the car, same day i bought it! although i drove it to home on CNG! it had an awesome pick even on CNG!
Mileage on ODO was 54300km!! I am currently driving it on 70% petrol and 30% Hi-Octane. have not driven it much! but a rough idea is that its giving arnd 9.5 to 10km per litre.
The car very well maintained!! and my experience soo far is great!! loving each and every thing of it! the drive, the comfort, acceleration, gear smoothness, interior everything!! Soo far, i am happy that i put my money on a rite thing!
