If you are buying an Indica Xeta from Shraddha Motors, Bharuch, It is my personal recommendation that please do not have the car converted to CNG at the SHOWROOM i.e. Shraddha Motors because they do not have experienced CNG mechanics --
Installation part is OK they will install the CNG kit and deliver the vehicle however, the main technic comes when you car is not properly tuned up or the mechanic does not know which MIXER to be used. I had my car converted to CNG at Shraddha Motors however, the car engine stopped when I pressed the clutch even at the speed of 60 kmph. I gave 3 months time and more that 5 visits to the showroom but they could not pin point or resolve the problem.
Then I got my vehicle checked by a local CNG Kit fitter at Ankleshwar, and he charged my some money, he also changed the MIXER, and the problem was solved... hence please do not have your Indica Xeta car converted to CNG at Shraddha Motors.
