excellent car to buy for a middle class family....

We got our car 2 weeks ago. the car is doin very well. mileage is around 15 which i hope to improve after first service. the car is very spacious and acomodates 5 members comfortably. runs well. very stable at high speeds too. and driving is pleasure on highways. with petrol rates reachin nearly 60 rs i think diesel is a better option. but only prob is that the vehicle needs to keep running regularly for less maintainence cost.
Good fuel economy,good stability,very spacious.Bad interiors
