Value for money

Car is very good mileage is awesome but the only problem is that whenever we are changing it the 'no' is coming from my engine and also company provided tire is very low quality in a 30000 they got soft and cracked also in a city CNG mileage is between 18 to 20 and on the highway it is 23 to 25 as I am residing in a Maharashtra CNG price are 92 rupees so running cost almost 6 rupees but if we are purchasing diesel car then it is same rupees per running kilometre cost so it's our choice whenever the CNG will go down then automatically this car will be more efficient and economical
