I purchased J CVT in December 2018 and have driven more than 15000 km's. City mileage is 12 to 14 km/l and on highway. it has returned 18 to 20 km/l. I had considered City, Ciaz and S cross but in terms of safety and comfort. it's the best lowest maintenance cost in the segment. Decent performance. Cabin is silent and build quality is better than other cars in segment.
