There is no need to introduce the swift to India. Its a car that all we know. But talking about the difference between vxi and vdi its depend on what you need. If you are a person who spend more time in your car then go for vdi. As vdi gives you more mileage but on the other hand vxi is more comfortable at all points. Talking about the maintanance. Vxi is low maintanance car whereas vdi is more. The price of vdi’s parts is more then vxi. And vdi needs to be run in every 2 days as its engine starts with fuel burning whereas vxi is good as you can let it go for 10 days without any problem. So in short just for 3-4 kms more mileage do not go for vdi. Go for vxi you will get more comfort on money and engine.
