WagnoR as such is very good vehicle to have for the price that you shell out of your pockets. But Maruti cheats the consumer by giving the USB button to the integrated music system that comes in VXI Model. The fact is that the USB button is a dummy one you need to attach a separate USB adapter to it which would cost 4999/- just an adapter: (If the adapter has to be purchased separately why should it give the USB button to the music panel).
I got so much disappointed when I checked the price of that adapter, as we get new music system by investing the same price.
So be aware of this fact before you opt VXI model and sound output of the music system is also not so great. I bought the car just 2 month ago. I don’t find any other issues.
