Out of WagonR CNG & Celerio CNG, which would be the best buy? What are the differences between these 2 models. What is the life of company fitted CNG kit? Is selecting CNG car for city drive beneficial? Do we have to take additional care of CNG cars than petrol one? Does CNG have any negative effect on the engine or on its maintenance? Is maintenance cost of CNG car more as compared to petrol car? Please answer my above queries
