The cars look is extremely unpleasing. From the sides to top the curves are less. The rear also has so less curves that appears as the corners are bulging out. If the company wants to target middle class too, the mileage needs to be improved. A few inches increase in wheel diameter, curved edges, providing a little more width at the bottom and small extension to rear will make it more spacious, give more ground clearance, help in increasing curves and mileage and pick-up.
Expenditure on advertisement should be reduced and customers should be offered at lower prices. Increasing the engine efficiency can further help.
