Petrol Car in range of 5 to 7 lakhs


I want to purchase a car petrol (with good millage) in price range of Rs. 5 to 7 Lakhs.
I am confuse between Baleno - Delta, I20- Sports, Xcent – S 1.2, Jazz. It came to me that Baleno due to low kerb weight shake after speed of 120 km and some other problem and I20 is little bit costly as compare to Baleno specification comparison. But Baleno average is good among all. I want to buy a value for money car and after sale cost also minimum.
