I have coax vxi+ petrol verient. After using one year I am observing lot of vibrations inside and also I am getting lot of sound from dash board, I complained to Marti Suzuki even they are not able to resolve it . Two of my friends having same car even they are facing same issue. The quality of plastic they used inside is very of very low quality it may break if you press hard. One of the major problem is if you cross 60 km speed you will feel like you are sitting in a diesel vehicle. The engine sound is very loud inside for this problem I got answer from Maruti is "Sir dont compare this car with Honda and Hyundai cars" I am suggesting not to purchase this car.
