Good and comfort

Hi, I m from Coimbatore, I bought this car on 13th June 18, delta CVT model, now I reached 1000km only, driving experince is good, comfort is nice, interior and exterior look is superb. But only bad is milage I got only 12km for petrol. I expect 18per lit. I may come on after 2nd service, then one more think need to write it's service is nice but cost is high, service engineers response is good. Keep it up.
