I am planning to buy a new car for my family. So far I have zeroed on Swift as it has a nice sporty look and is spacious and suits my built 
Car would usually be driven by my Dad/brother (NCR) monthly kms done should be around 1000 with long route may be once in a month or three.
Budget as of now is 4.5L but can stretch to 5L
Now the confusion which I have is which model to go for and which one would end being VFM and have most mileage.
Vxi/Zxi does not have much difference apart from the Zxi looking much more loaded in terms of accessories and features but being a Petrol version cost of fuel would be more as compared to diesel.
Vdi (well this is the one which I really want to go for) have heard lot of good word for this model but on road this would end like around 5.5L (is it worth spending 5.5L?) and it does not have the extra features like Zxi though it is costlier.
Can any one guide me which one to go for, esp those who have these models??
