I have grand I 10 for more then 9 months and its mileage is decreased from 23 to 18 km per litre of petrol. I don’t why this happening even I am doing regular services on time. Inside cabin space is spacious and sufficient for 3 aduts in back seat and even leg room is spacious for 6.2 feet tall man. Interior has good quality material all around in car and finish is excellent. Audio quality is not too good. Hyundai is a reliable and perfect brand for both luxury and passion. Looks are impressive as usual in hyundai cars.
